getwc - get a wide character from a stream
#include <stdio.h>
#include <wchar.h>
wint_t getwc(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 IEEE Std 1003.1-2001 defers to the ISO C standard.The getwc() function shall be equivalent to fgetwc(), 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 fgetwc().
Refer to fgetwc().
None.
Since it may be implemented as a macro, getwc() may treat incorrectly a stream argument with side effects. In particular, getwc(*f++) does not necessarily work as expected. Therefore, use of this function is not recommended; fgetwc() should be used instead.
