Originální popis anglicky: putwc - put a wide character on a stream

Návod, kniha: POSIX Programmer's Manual

STRUČNĚ

#include <stdio.h> #include <wchar.h> wint_t putwc(wchar_t wc, FILE *stream);

POPIS / INSTRUKCE

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.

NÁVRATOVÁ HODNOTA

Refer to fputwc() .

CHYBY / ERRORY

Refer to fputwc() . The following sections are informative.

PŘÍKLADY POUŽITÍ

None.

APPLICATION USAGE

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.

RATIONALE

None.

FUTURE DIRECTIONS

None.
