GETC(3)			  OpenBSD Programmer's Manual		       GETC(3)

NAME
     fgetc, getc, getchar, getw - get next character or word from input stream

SYNOPSIS
     #include <stdio.h>

     int
     fgetc(FILE *stream);

     int
     getc(FILE *stream);

     int
     getchar(void);

     int
     getw(FILE *stream);

DESCRIPTION
     The fgetc() function obtains the next input character (if present) from
     the stream pointed at by stream, or the next character pushed back on the
     stream via ungetc(3).

     The getc() function acts essentially identically to fgetc(), but is a
     macro that expands in-line.

     The getchar() function is equivalent to getc() with the argument stdin.

     The getw() function obtains the next int (if present) from the stream
     pointed at by stream.

RETURN VALUES
     If successful, these routines return the next requested object from the
     stream.  If the stream is at end-of-file or a read error occurs, the
     routines return EOF.  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 EOF until the condition is cleared with clearerr(3).

SEE ALSO
     ferror(3), fopen(3), fread(3), putc(3), ungetc(3)

STANDARDS
     The fgetc(), getc(), and getchar() functions conform to ANSI X3.159-1989
     (``ANSI C'').

BUGS
     Since EOF is a valid integer value, feof(3) and ferror(3) must be used to
     check for failure after calling getw().

     Since the size and byte order of an int may vary from one machine to
     another, getw() is not recommended for portable applications.
