FWIDE(3) Library Functions Manual FWIDE(3) NAME fwide - get/set orientation of a stream LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <stdio.h> #include <wchar.h> int fwide(FILE *stream, int mode); DESCRIPTION The fwide() function determines the orientation of the stream pointed at by stream. If the orientation of stream has already been determined, fwide() leaves it unchanged. Otherwise, fwide() sets the orientation of stream according to mode. If mode is less than zero, stream is set to byte-oriented. If it is greater than zero, stream is set to wide-oriented. Otherwise, mode is zero, and stream is unchanged. RETURN VALUES fwide() returns a value according to orientation after the call of fwide(); a value less than zero if byte-oriented, a value greater than zero if wide-oriented, and zero if the stream has no orientation. SEE ALSO ferror(3), fgetc(3), fgetwc(3), fopen(3), fputc(3), fputwc(3), freopen(3), stdio(3) STANDARDS The fwide() function conforms to ISO/IEC 9899:1999 ("ISO C99").
