NAME
fgetwc, getwc - read a wide character from a FILE streamSYNOPSIS
#include <stdio.h>
#include <wchar.h> wint_t fgetwc(FILE *stream); wint_t getwc(FILE *stream);
DESCRIPTION
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).
RETURN VALUE
The fgetwc() function returns the next wide-character from the stream, or WEOF.ERRORS
Apart from the usual ones, there is- EILSEQ
- The data obtained from the input stream does not form a valid character.
CONFORMING TO
C99, POSIX.1-2001.NOTES
The behavior of fgetwc() depends on the LC_CTYPE category of the current locale.In the absence of additional information passed to the fopen(3) call, it is reasonable to expect that fgetwc() will actually read a multibyte sequence from the stream and then convert it to a wide character.
