GETWC(3) BSD Programmer's Manual GETWC(3)NAME
fgetwc, getwc, getwchar - get next wide-character from input stream
SYNOPSIS
#include <stdio.h>
#include <wchar.h>
wint_t
fgetwc(FILE *stream);
wint_t
getwc(FILE *stream);
wint_t
getwchar();
DESCRIPTION
The fgetwc() function obtains the next input wide-character (if present)
from the stream pointed at by stream, or the next character pushed back
on the stream via ungetwc(3).
The getwc() function acts essentially identically to fgetwc(), but is a
macro that expands in-line.
The getwchar() function is equivalent to getwc() with the argument stdin.
RETURN VALUES
If successful, these routines return the next wide-character from the
stream. If the stream is at end-of-file or a read error occurs, the rou-
tines return WEOF. The routines feof(3) and ferror(3) must be used to
distinguish between end-of-file and error. If an error occurs, the global
variable errno is set to indicate the error. The end-of-file condition is
remembered, even on a terminal, and all subsequent attempts to read will
return WEOF until the condition is cleared with clearerr(3).
SEE ALSOferror(3), fopen(3), fread(3), putwc(3), stdio(3), ungetwc(3)STANDARDS
The fgetwc(), getwc() and getwchar() functions conform to ISO/IEC
9899:1999 ("ISO C99").
In addition to the standard, the MirOS implementation allows continuation
after an illegal input sequence (when WEOF is returned, ferror(3) returns
non-zero, and errno is set to EILSEQ). Also, mixing wide-oriented and
byte-oriented I/O functions is possible.
