getwchar - get wide character from stdin stream SYNOPSIS
#include <wchar.h> wint_t getwchar(void) DESCRIPTION
The getwchar() function is equivalent to getwc(stdin). RETURN VALUES
Refer to fgetwc(3C). ERRORS
Refer to fgetwc(3C). USAGE
If the wint_t value returned by getwchar() is stored into a variable of type wchar_t and then compared against the wint_t macro WEOF, the comparison may never succeed because wchar_t is defined as unsigned. ATTRIBUTES

fgetwc, getwc, getwchar, -- get next wide character from input stream LIBRARY
Standard C Library (libc, -lc) 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 routines 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 ALSO
ferror(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'') and IEEE Std 1003.1-2001 (``POSIX.1''). BSD
