fgetwc, getwc - read a wide character from a FILE stream
#include <stdio.h> #include <wchar.h> wint_t fgetwc(FILE *stream); wint_t getwc(FILE *stream);
The fgetwc() function is the wide-character equivalent of the fgetc(3) function. It reads a wide character from
stream and returns it. If the end of stream is reached, or if
ferror(stream) becomes true, it returns WEOF. If a wide-character conversion error occurs, it sets
errno to EILSEQ and returns WEOF.
The getwc() function or macro functions identically to fgetwc(). It may be implemented as a macro, and may evaluate its argument more than once. There is no reason ever to use it.
For nonlocking counterparts, see unlocked_stdio(3).
The fgetwc() function returns the next wide-character from the stream, or WEOF. In the event of an error,
errno is set to indicate the cause.
Apart from the usual ones, there is
The data obtained from the input stream does not form a valid character.
