---|
4 | <<getline>>---read a line from a file |

---|
9 | SYNOPSIS |
---|
10 | #include <stdio.h> |
---|
11 | ssize_t getline(char **<[bufptr]>, size_t *<[n]>, FILE *<[fp]>); |
---|
12 | |
---|
13 | DESCRIPTION |
---|
14 | <<getline>> reads a file <[fp]> up to and possibly including the |
---|
15 | newline character. The line is read into a buffer pointed to |
---|
16 | by <[bufptr]> and designated with size *<[n]>. If the buffer is |
---|
17 | not large enough, it will be dynamically grown by <<getdelim>>. |
---|
18 | As the buffer is grown, the pointer to the size <[n]> will be |
---|
19 | updated. |
---|
20 | |
---|
21 | <<getline>> is equivalent to getdelim(bufptr, n, '\n', fp); |
---|
22 | |
---|
23 | RETURNS |
---|
24 | <<getline>> returns <<-1>> if no characters were successfully read, |
---|
25 | otherwise, it returns the number of bytes successfully read. |
---|
26 | at end of file, the result is nonzero. |
---|
27 | |
---|
28 | PORTABILITY |
---|
29 | <<getline>> is a glibc extension. |
---|
30 | |
---|
31 | No supporting OS subroutines are directly required. |
