       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


       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.
