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 in‐
put 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.
