PUTWC(3P) POSIX Programmer's Manual PUTWC(3P)
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
putwc — put a wide character on a stream
#include <stdio.h> #include <wchar.h> wint_t putwc(wchar_t wc, FILE *stream);
The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1‐2008 defers to the ISO C standard. The putwc() function shall be equivalent to fputwc(), except that if it is implemented as a macro it may evaluate stream more than once, so the argument should never be an expression with side-effects.
Refer to fputwc(3p).
Refer to fputwc(3p). The following sections are informative.
None.
Since it may be implemented as a macro, putwc() may treat a stream argument with side-effects incorrectly. In particular, putwc(wc,*f++) need not work correctly. Therefore, use of this function is not recommended; fputwc() should be used instead.
None.
None.
