PUTS(3)                    Linux Programmer's Manual                   PUTS(3)



 

NAME


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

 

SYNOPSIS


       #include 

       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 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 non-locking counterparts, see unlocked_stdio(3).

 

RETURN VALUE


       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 non-negative number on success, or EOF on
       error.

 

CONFORMING TO


       C89, C99.

 

BUGS


       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 asso-
       ciated with the same output stream; the results will be  undefined  and
       very probably not what you want.
