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