| 40 | SYNOPSIS |
---|
| 41 | #include <wchar.h> |
---|
| 42 | int fputws(const wchar_t *__restrict <[ws]>, FILE *__restrict <[fp]>); |
---|
| 43 | |
---|
| 44 | #define _GNU_SOURCE |
---|
| 45 | #include <wchar.h> |
---|
| 46 | int fputws_unlocked(const wchar_t *__restrict <[ws]>, FILE *__restrict <[fp]>); |
---|
| 47 | |
---|
| 48 | #include <wchar.h> |
---|
| 49 | int _fputws_r(struct _reent *<[ptr]>, const wchar_t *<[ws]>, |
---|
| 50 | FILE *<[fp]>); |
---|
| 51 | |
---|
| 52 | #include <wchar.h> |
---|
| 53 | int _fputws_unlocked_r(struct _reent *<[ptr]>, const wchar_t *<[ws]>, |
---|
| 54 | FILE *<[fp]>); |
---|
| 55 | |
---|
| 56 | DESCRIPTION |
---|
| 57 | <<fputws>> writes the wide character string at <[ws]> (but without the |
---|
| 58 | trailing null) to the file or stream identified by <[fp]>. |
---|
| 59 | |
---|
| 60 | <<fputws_unlocked>> is a non-thread-safe version of <<fputws>>. |
---|
| 61 | <<fputws_unlocked>> may only safely be used within a scope |
---|
| 62 | protected by flockfile() (or ftrylockfile()) and funlockfile(). This |
---|
| 63 | function may safely be used in a multi-threaded program if and only |
---|
| 64 | if they are called while the invoking thread owns the (FILE *) |
---|
| 65 | object, as is the case after a successful call to the flockfile() or |
---|
| 66 | ftrylockfile() functions. If threads are disabled, then |
---|
| 67 | <<fputws_unlocked>> is equivalent to <<fputws>>. |
---|
| 68 | |
---|
| 69 | <<_fputws_r>> and <<_fputws_unlocked_r>> are simply reentrant versions of the |
---|
| 70 | above that take an additional reentrant struct pointer argument: <[ptr]>. |
---|
| 71 | |
---|
| 72 | RETURNS |
---|
| 73 | If successful, the result is a non-negative integer; otherwise, the result |
---|
| 74 | is <<-1>> to indicate an error. |
---|
| 75 | |
---|
| 76 | PORTABILITY |
---|
| 77 | <<fputws>> is required by C99 and POSIX.1-2001. |
---|
| 78 | |
---|
| 79 | <<fputws_unlocked>> is a GNU extension. |
