FGETWC(3)						     Linux Programmer's Manual							 FGETWC(3)

NAME
fgetwc, getwc - read a wide character from a FILE stream SYNOPSIS
#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. 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. ATTRIBUTES

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 multi- byte sequence from the stream and then convert it to a wide character. SEE ALSO

NAME
fputwc, putwc - write a wide character to a FILE stream SYNOPSIS
#include <stdio.h> #include <wchar.h> wint_t fputwc(wchar_t wc, FILE *stream); wint_t putwc(wchar_t wc, FILE *stream); DESCRIPTION
The fputwc() function is the wide-character equivalent of the fputc(3) function. It writes the wide character wc to stream. If fer- ror(stream) becomes true, it returns WEOF. If a wide-character conversion error occurs, it sets errno to EILSEQ and returns WEOF. Other- wise, it returns wc. The putwc() function or macro functions identically to fputwc(). 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 fputwc() function returns wc if no error occurred, or WEOF to indicate an error. In the event of an error, errno is set to indicate the cause. ERRORS
Apart from the usual ones, there is EILSEQ Conversion of wc to the stream's encoding fails. ATTRIBUTES
