NAME

fputc, fputs, putc, putchar, puts - output of characters and strings  

SYNOPSIS

#include <stdio.h>int fputc(int c, FILE *stream);int fputs(const char *s, FILE *stream);int putc(int c, FILE *stream);int putchar(int c);int puts(const char *s);
 

DESCRIPTION

fputc() writes the character c, cast to an unsigned char, to stream.

fputs() writes the string sto stream, without its terminating null byte (aq\0aq).

putc() is equivalent to fputc() except that it may be implemented as a macro which evaluates streammore than once.

putchar(c)is equivalent to putc(c, stdout).

puts() writes the string sand a trailing newline to stdout.

Calls to the functions described here can be mixed with each other and with calls to other output functions from the stdiolibrary for the same output stream.

For nonlocking counterparts, see unlocked_stdio(3).  

RETURN VALUE

fputc(), putc() and putchar() return the character written as an unsigned charcast to an intor EOFon error.

puts() and fputs() return a nonnegative number on success, or EOFon error.

BUGS

It is not advisable to mix calls to output functions from the stdiolibrary with low-level calls to write(2) for the file descriptor associated with the same output stream; the results will be undefined and very probably not what you want.
