GETC(3S)                COMMAND REFERENCE                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 word (in a 32-bit integer) 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 success of
     getw.  Getw assumes no special alignment in the file.

DIAGNOSTICS
     These functions return the integer constant EOF at end-of-
     file or upon read error.

     A stop, with the message, Reading bad file, means an attempt
     has been made to read from a stream that has not been opened
     for reading by fopen.

CAVEATS
     The end-of-file return from getchar is incompatible with
     that in UNIX editions 1-6.

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

SEE ALSO
     fopen(3s), putc(3s), gets(3s), scanf(3s), fread(3s), and
     ungetc(3s).
