PUTS(3) Linux Programmer's Manual PUTS(3)
fputc, fputs, putc, putchar, puts - output of characters and strings
#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);
fputc() writes the character c, cast to an unsigned char, to stream.
fputs() writes the string s to stream, without its trailing '\0'.
putc() is equivalent to fputc() except that it may be implemented as a macro
which evaluates stream more than once.
putchar(c); is equivalent to putc(c,stdout).
puts() writes the string s and 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 stdio library for the same output
stream.
For nonlocking counterparts, see unlocked_stdio(3).
fputc(), putc() and putchar() return the character written as an unsigned char
cast to an int or EOF on error.
puts() and fputs() return a nonnegative number on success, or EOF on error.
C89, C99.
It is not advisable to mix calls to output functions from the stdio library
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.
