putc(3s) putc(3s)
Name
putc, putchar, fputc, putw - put character or word on a stream
Syntax
#include <stdio.h>
int putc(c, stream)
char c;
FILE *stream;
putchar(c)
fputc(c, stream)
FILE *stream
putw(w, stream)
FILE *stream;
Description
The routine appends the character c to the named output stream. It returns the character written.
The routine is defined as (c, stdout).
The routine behaves like but is a genuine function rather than a macro.
The routine appends word (that is, int) w to the output stream. It returns zero. The routine neither assumes nor causes special alignment
in the file.
Restrictions
Because it is implemented as a macro, treats a stream argument with side effects incorrectly. In particular, `putc(c, *f++);' doesn't work
as expected.
Diagnostics
The and functions return the constant EOF upon error. The function returns a non-zero value on error.
