putwc — put a wide character on a stream
#include <stdio.h>
#include <wchar.h>
wint_t putwc(wchar_t wc, FILE *stream);
[CX] 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.1-2024 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 .
Refer to fputwc .
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.
First released as a World-wide Portability Interface in Issue 4.
Aligned with ISO/IEC 9899:1990/Amendment 1:1995 (E). Specifically, the type of argument wc is changed from wint_t to wchar_t.
The Optional Header (OH) marking is removed from <stdio.h>.
POSIX.1-2008, Technical Corrigendum 1, XSH/TC1-2008/0478 [14] is applied.
