| |
| DESCRIPTION |
| <<fputws>> writes the wide character string at <[ws]> (but without the |
| trailing null) to the file or stream identified by <[fp]>. |
| |
| <<fputws_unlocked>> is a non-thread-safe version of <<fputws>>. |
| <<fputws_unlocked>> may only safely be used within a scope |
| protected by flockfile() (or ftrylockfile()) and funlockfile(). This |
| function may safely be used in a multi-threaded program if and only |
| if they are called while the invoking thread owns the (FILE *) |
| object, as is the case after a successful call to the flockfile() or |
| ftrylockfile() functions. If threads are disabled, then |
| <<fputws_unlocked>> is equivalent to <<fputws>>. |
| |
| <<_fputws_r>> and <<_fputws_unlocked_r>> are simply reentrant versions of the |
| above that take an additional reentrant struct pointer argument: <[ptr]>. |
| |
| RETURNS |
| If successful, the result is a non-negative integer; otherwise, the result |
| is <<-1>> to indicate an error. |
| |
| PORTABILITY |
| <<fputws>> is required by C99 and POSIX.1-2001. |
| |
| <<fputws_unlocked>> is a GNU extension. |
