GETC(3S)	    UNIX Programmer's Manual		 GETC(3S)


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

SYNOPSIS
     #include <stdio.h>

     int getc(stream)
     FILE *stream;

     int getchar()

     int fgetc(stream)
     FILE *stream;

     int getw(stream)
     FILE *stream;

DESCRIPTION
     Getc returns the next character from the named input stream.

     Getchar() is identical to getc(stdin).

     Fgetc behaves like getc, but is a genuine function, not a
     macro; it may be used to save object text.

     Getw returns the next int (a 32-bit integer on a VAX-11)
     from the named input stream.  It returns the constant EOF
     upon end of file or error, but since that is a good integer
     value, feof and ferror(3S) should be used to check the suc-
     cess of getw.  Getw assumes no special alignment in the
     file.

SEE ALSO
     clearerr(3S), fopen(3S), putc(3S), gets(3S), scanf(3S),
     fread(3S), ungetc(3S)

DIAGNOSTICS
     These functions return the integer constant EOF at end of
     file, upon read error, or if an attempt is made to read a
     file not opened by fopen.	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(3S).

BUGS
     Because it is implemented as a macro, getc treats a stream
     argument with side effects incorrectly.  In particular,
     `getc(*f++);' doesn't work sensibly.
