GETC(3S) 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 (32-bit integer on a VAX) 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(3) should be used to check the success of
getw. Getw assumes no special alignment in the file.
SEE ALSO
fopen(3), putc(3), gets(3), scanf(3), fread(3), ungetc(3)
DIAGNOSTICS
These functions return the integer constant EOF at end of
file or upon read error.
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.
