       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 terminating null byte ('\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.

       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.

       putwchar(3), scanf(3), unlocked_stdio(3)
