28 | SYNOPSIS |
---|
29 | #include <time.h> |
---|
30 | size_t strftime(char *restrict <[s]>, size_t <[maxsize]>, |
---|
31 | const char *restrict <[format]>, |
---|
32 | const struct tm *restrict <[timp]>); |
---|
33 | size_t strftime_l(char *restrict <[s]>, size_t <[maxsize]>, |

---|
35 | const struct tm *restrict <[timp]>, |
---|
36 | locale_t <[locale]>); |
---|
37 | |
---|
38 | DESCRIPTION |
---|
39 | <<strftime>> converts a <<struct tm>> representation of the time (at |
---|
40 | <[timp]>) into a null-terminated string, starting at <[s]> and occupying |
---|
41 | no more than <[maxsize]> characters. |
---|
42 | |
---|
43 | <<strftime_l>> is like <<strftime>> but creates a string in a format |
---|
44 | as expected in locale <[locale]>. If <[locale]> is LC_GLOBAL_LOCALE or |
---|
45 | not a valid locale object, the behaviour is undefined. |
---|
46 | |
---|
47 | You control the format of the output using the string at <[format]>. |
---|
48 | <<*<[format]>>> can contain two kinds of specifications: text to be |
---|
49 | copied literally into the formatted string, and time conversion |
---|
50 | specifications. Time conversion specifications are two- and |
---|
51 | three-character sequences beginning with `<<%>>' (use `<<%%>>' to |
---|
52 | include a percent sign in the output). Each defined conversion |
---|
53 | specification selects only the specified field(s) of calendar time |
---|
54 | data from <<*<[timp]>>>, and converts it to a string in one of the |
---|
55 | following ways: |
---|
56 | |
---|
57 | o+ |
---|
58 | o %a |
---|
59 | The abbreviated weekday name according to the current locale. [tm_wday] |
---|
60 | |
---|
61 | o %A |
---|
62 | The full weekday name according to the current locale. |
---|
63 | In the default "C" locale, one of `<<Sunday>>', `<<Monday>>', `<<Tuesday>>', |
---|
64 | `<<Wednesday>>', `<<Thursday>>', `<<Friday>>', `<<Saturday>>'. [tm_wday] |
---|
65 | |
---|
66 | o %b |
---|
67 | The abbreviated month name according to the current locale. [tm_mon] |
---|
68 | |
---|
69 | o %B |
---|
70 | The full month name according to the current locale. |
---|
71 | In the default "C" locale, one of `<<January>>', `<<February>>', |
---|
72 | `<<March>>', `<<April>>', `<<May>>', `<<June>>', `<<July>>', |
---|
73 | `<<August>>', `<<September>>', `<<October>>', `<<November>>', |
---|
74 | `<<December>>'. [tm_mon] |
---|
75 | |
---|
76 | o %c |
---|
77 | The preferred date and time representation for the current locale. |
---|
78 | [tm_sec, tm_min, tm_hour, tm_mday, tm_mon, tm_year, tm_wday] |
---|
79 | |
---|
80 | o %C |
---|
81 | The century, that is, the year divided by 100 then truncated. For |
---|
82 | 4-digit years, the result is zero-padded and exactly two characters; |
---|
83 | but for other years, there may a negative sign or more digits. In |
---|
84 | this way, `<<%C%y>>' is equivalent to `<<%Y>>'. [tm_year] |
---|
85 | |
---|
86 | o %d |
---|
87 | The day of the month, formatted with two digits (from `<<01>>' to |
---|
88 | `<<31>>'). [tm_mday] |
---|
89 | |
---|
90 | o %D |
---|
91 | A string representing the date, in the form `<<"%m/%d/%y">>'. |
---|
92 | [tm_mday, tm_mon, tm_year] |
---|
93 | |
---|
94 | o %e |
---|
95 | The day of the month, formatted with leading space if single digit |
---|
96 | (from `<<1>>' to `<<31>>'). [tm_mday] |
---|
97 | |
---|
98 | o %E<<x>> |
---|
99 | In some locales, the E modifier selects alternative representations of |
---|
100 | certain modifiers <<x>>. In newlib, it is ignored, and treated as %<<x>>. |
---|
101 | |
---|
102 | o %F |
---|
103 | A string representing the ISO 8601:2000 date format, in the form |
---|
104 | `<<"%Y-%m-%d">>'. [tm_mday, tm_mon, tm_year] |
---|
105 | |
---|
106 | o %g |
---|
107 | The last two digits of the week-based year, see specifier %G (from |
---|
108 | `<<00>>' to `<<99>>'). [tm_year, tm_wday, tm_yday] |
---|
109 | |
---|
110 | o %G |
---|
111 | The week-based year. In the ISO 8601:2000 calendar, week 1 of the year |
---|
112 | includes January 4th, and begin on Mondays. Therefore, if January 1st, |
---|
113 | 2nd, or 3rd falls on a Sunday, that day and earlier belong to the last |
---|
114 | week of the previous year; and if December 29th, 30th, or 31st falls |
---|
115 | on Monday, that day and later belong to week 1 of the next year. For |
---|
116 | consistency with %Y, it always has at least four characters. |
---|
117 | Example: "%G" for Saturday 2nd January 1999 gives "1998", and for |
---|
118 | Tuesday 30th December 1997 gives "1998". [tm_year, tm_wday, tm_yday] |
---|
119 | |
---|
120 | o %h |
---|
121 | Synonym for "%b". [tm_mon] |
---|
122 | |
---|
123 | o %H |
---|
124 | The hour (on a 24-hour clock), formatted with two digits (from |
---|
125 | `<<00>>' to `<<23>>'). [tm_hour] |
---|
126 | |
---|
127 | o %I |
---|
128 | The hour (on a 12-hour clock), formatted with two digits (from |
---|
129 | `<<01>>' to `<<12>>'). [tm_hour] |
---|
130 | |
---|
131 | o %j |
---|
132 | The count of days in the year, formatted with three digits |
---|
133 | (from `<<001>>' to `<<366>>'). [tm_yday] |
---|
134 | |
---|
135 | o %k |
---|
136 | The hour (on a 24-hour clock), formatted with leading space if single |
---|
137 | digit (from `<<0>>' to `<<23>>'). Non-POSIX extension (c.p. %I). [tm_hour] |
---|
138 | |
---|
139 | o %l |
---|
140 | The hour (on a 12-hour clock), formatted with leading space if single |
---|
141 | digit (from `<<1>>' to `<<12>>'). Non-POSIX extension (c.p. %H). [tm_hour] |
---|
142 | |
---|
143 | o %m |
---|
144 | The month number, formatted with two digits (from `<<01>>' to `<<12>>'). |
---|
145 | [tm_mon] |
---|
146 | |
---|
147 | o %M |
---|
148 | The minute, formatted with two digits (from `<<00>>' to `<<59>>'). [tm_min] |
---|
149 | |
---|
150 | o %n |
---|
151 | A newline character (`<<\n>>'). |
---|
152 | |
---|
153 | o %O<<x>> |
---|
154 | In some locales, the O modifier selects alternative digit characters |
---|
155 | for certain modifiers <<x>>. In newlib, it is ignored, and treated as %<<x>>. |
---|
156 | |
---|
157 | o %p |
---|
158 | Either `<<AM>>' or `<<PM>>' as appropriate, or the corresponding strings for |
---|
159 | the current locale. [tm_hour] |
---|
160 | |
---|
161 | o %P |
---|
162 | Same as '<<%p>>', but in lowercase. This is a GNU extension. [tm_hour] |
---|
163 | |
---|
164 | o %r |
---|
165 | Replaced by the time in a.m. and p.m. notation. In the "C" locale this |
---|
166 | is equivalent to "%I:%M:%S %p". In locales which don't define a.m./p.m. |
---|
167 | notations, the result is an empty string. [tm_sec, tm_min, tm_hour] |
---|
168 | |
---|
169 | o %R |
---|
170 | The 24-hour time, to the minute. Equivalent to "%H:%M". [tm_min, tm_hour] |
---|
171 | |
---|
172 | o %s |
---|
173 | The time elapsed, in seconds, since the start of the Unix epoch at |
---|

---|
175 | |
---|
176 | o %S |
---|
177 | The second, formatted with two digits (from `<<00>>' to `<<60>>'). The |
---|
178 | value 60 accounts for the occasional leap second. [tm_sec] |
---|
179 | |
---|
180 | o %t |
---|
181 | A tab character (`<<\t>>'). |
---|
182 | |
---|
183 | o %T |
---|
184 | The 24-hour time, to the second. Equivalent to "%H:%M:%S". [tm_sec, |
---|
185 | tm_min, tm_hour] |
---|
186 | |
---|
187 | o %u |
---|
188 | The weekday as a number, 1-based from Monday (from `<<1>>' to |
---|
189 | `<<7>>'). [tm_wday] |
---|
190 | |
---|
191 | o %U |
---|
192 | The week number, where weeks start on Sunday, week 1 contains the first |
---|
193 | Sunday in a year, and earlier days are in week 0. Formatted with two |
---|
194 | digits (from `<<00>>' to `<<53>>'). See also <<%W>>. [tm_wday, tm_yday] |
---|
195 | |
---|
196 | o %V |
---|
197 | The week number, where weeks start on Monday, week 1 contains January 4th, |
---|
198 | and earlier days are in the previous year. Formatted with two digits |
---|
199 | (from `<<01>>' to `<<53>>'). See also <<%G>>. [tm_year, tm_wday, tm_yday] |
---|
200 | |
---|
201 | o %w |
---|
202 | The weekday as a number, 0-based from Sunday (from `<<0>>' to `<<6>>'). |
---|
203 | [tm_wday] |
---|
204 | |
---|
205 | o %W |
---|
206 | The week number, where weeks start on Monday, week 1 contains the first |
---|
207 | Monday in a year, and earlier days are in week 0. Formatted with two |
---|
208 | digits (from `<<00>>' to `<<53>>'). [tm_wday, tm_yday] |
---|
209 | |
---|
210 | o %x |
---|
211 | Replaced by the preferred date representation in the current locale. |
---|
212 | In the "C" locale this is equivalent to "%m/%d/%y". |
---|
213 | [tm_mon, tm_mday, tm_year] |
---|
214 | |
---|
215 | o %X |
---|
216 | Replaced by the preferred time representation in the current locale. |
---|
217 | In the "C" locale this is equivalent to "%H:%M:%S". [tm_sec, tm_min, tm_hour] |
---|
218 | |
---|
219 | o %y |
---|
220 | The last two digits of the year (from `<<00>>' to `<<99>>'). [tm_year] |
---|
221 | (Implementation interpretation: always positive, even for negative years.) |
---|
222 | |
---|
223 | o %Y |
---|
224 | The full year, equivalent to <<%C%y>>. It will always have at least four |
---|
225 | characters, but may have more. The year is accurate even when tm_year |
---|
226 | added to the offset of 1900 overflows an int. [tm_year] |
---|
227 | |
---|
228 | o %z |
---|
229 | The offset from UTC. The format consists of a sign (negative is west of |
---|
230 | Greewich), two characters for hour, then two characters for minutes |
---|
231 | (-hhmm or +hhmm). If tm_isdst is negative, the offset is unknown and no |
---|
232 | output is generated; if it is zero, the offset is the standard offset for |
---|
233 | the current time zone; and if it is positive, the offset is the daylight |
---|
234 | savings offset for the current timezone. The offset is determined from |
---|
235 | the TZ environment variable, as if by calling tzset(). [tm_isdst] |
---|
236 | |
---|
237 | o %Z |
---|
238 | The time zone name. If tm_isdst is negative, no output is generated. |
---|
239 | Otherwise, the time zone name is based on the TZ environment variable, |
---|
240 | as if by calling tzset(). [tm_isdst] |
---|
241 | |
---|
242 | o %% |
---|
243 | A single character, `<<%>>'. |
---|
244 | o- |
---|
245 | |
---|
246 | RETURNS |
---|
247 | When the formatted time takes up no more than <[maxsize]> characters, |
---|
248 | the result is the length of the formatted string. Otherwise, if the |
---|
249 | formatting operation was abandoned due to lack of room, the result is |
---|
250 | <<0>>, and the string starting at <[s]> corresponds to just those |
---|
251 | parts of <<*<[format]>>> that could be completely filled in within the |
---|
252 | <[maxsize]> limit. |
---|
253 | |
---|
254 | PORTABILITY |
---|
255 | ANSI C requires <<strftime>>, but does not specify the contents of |
---|
256 | <<*<[s]>>> when the formatted string would require more than |
---|
257 | <[maxsize]> characters. Unrecognized specifiers and fields of |
---|
258 | <<timp>> that are out of range cause undefined results. Since some |
---|
259 | formats expand to 0 bytes, it is wise to set <<*<[s]>>> to a nonzero |
---|
260 | value beforehand to distinguish between failure and an empty string. |
---|
261 | This implementation does not support <<s>> being NULL, nor overlapping |
---|
262 | <<s>> and <<format>>. |
---|
263 | |
---|
264 | <<strftime_l>> is POSIX-1.2008. |
---|
265 | |
---|
266 | <<strftime>> and <<strftime_l>> require no supporting OS subroutines. |
---|
267 | |
---|
268 | BUGS |
---|
269 | (NOT Cygwin:) <<strftime>> ignores the LC_TIME category of the current |
---|
270 | locale, hard-coding the "C" locale settings. |
