-.Sh NAME
-.Nm fputc ,
-.Nm putc ,
-.Nm putchar ,
-.Nm putw
-.Nd output a character or word to a stream
-.Sh SYNOPSIS
-.Fd #include <stdio.h>
-.Ft int
-.Fn fputc "int c" "FILE *stream"
-.Ft int
-.Fn putc "int c" "FILE *stream"
-.Ft int
-.Fn putchar "int c"
-.Ft int
-.Fn putw "int w" "FILE *stream"
-.Sh DESCRIPTION
-The
-.Fn fputc
-function
-writes the character
-.Fa c
-(converted to an ``unsigned char'')
-to the output stream pointed to by
-.Fa stream .
-.Pp
-.Fn Putc
-acts essentially identically to
-.Fn fputc ,
-but is a macro that expands in-line. It may evaluate
-.Fa stream
-more than once, so arguments given to
-.Fn putc
-should not be expressions with potential side effects.
-.Pp
-.Fn Putchar
-is identical to
-.Fn putc
-with an output stream of
-.Em stdout .
-.Pp
-The
-.Fn putw
-function
-writes the specified
-.Em int
-to the named output
-.Fa stream .
-.Sh RETURN VALUES
-The functions,
-.Fn fputc ,
-.Fn putc
-and
-.Fn putchar
-return the character written.
-If an error occurs, the value
-.Dv EOF
-is returned.
-The
-.Fn putw
-function
-returns 0 on success;
-.Dv EOF
-is returned if
-a write error occurs,
-or if an attempt is made to write a read-only stream.
-.Sh SEE ALSO
-.Xr ferror 3 ,
-.Xr fopen 3 ,
-.Xr getc 3 ,
-.Xr stdio 3
-.Sh STANDARDS
-The functions
-.Fn fputc ,
-.Fn putc ,
-and
-.Fn putchar ,
-conform to
-.St -ansiC .
-A function
-.Fn putw
-function appeared in
-.At v6 .
-.Sh BUGS
-The size and byte order of an
-.Em int
-varies from one machine to another, and
-.Fn putw
-is not recommended for portable applications.
