NAME
     fputc, putc, putchar, putw - output a character or word to a stream

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <stdio.h>

     int
     fputc(int c, FILE *stream);

     int
     putc(int c, FILE *stream);

     int
     putchar(int c);

     int
     putw(int w, FILE *stream);

DESCRIPTION
     The fputc() function writes the character c (converted to an ``unsigned
     char'') to the output stream pointed to by stream.

     The putc() macro acts essentially identically to fputc(), but is a macro
     that expands in-line.  It may evaluate stream more than once, so argu-
     ments given to putc() should not be expressions with potential side
     effects.

     The putchar() macro is identical to putc() with an output stream of
     stdout.

     The putw() function writes the specified int to the named output stream.

RETURN VALUES
     The functions, fputc(), putc() and putchar() return the character writ-
     ten.  If an error occurs, the value EOF is returned.  The putw() function
     returns 0 on success; EOF is returned if a write error occurs, or if an
     attempt is made to write a read-only stream.

SEE ALSO
     ferror(3), fopen(3), getc(3), stdio(3)

STANDARDS
     The functions fputc(), putc(), and putchar(), conform to ISO/IEC
     9899:1990 (``ISO C89'').  A function putw() function appeared in
     Version 6 AT&T UNIX.

BUGS
     The size and byte order of an int varies from one machine to another, and
     putw() is not recommended for portable applications.
