NAME
fgetwc, getwc - read a wide character from a FILE stream SYNOPSIS
#include
#include
wintt fgetwc(FILE *stream); wintt 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 unlockedstdio(3). RETURN VALUE
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. ERRORS Apart from the usual ones, there is EILSEQ The data obtained from the input stream does not form a valid character.

C99, POSIX.1-2001. NOTES The behavior of fgetwc() depends on the LCCTYPE category of the cur‐ rent 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.
