Name
       putc, putchar, fputc, putw - put character or word on a stream

Syntax
       #include <stdio.h>

       int putc(c, stream)
       char c;
       FILE *stream;

       putchar(c)

       fputc(c, stream)
       FILE *stream

       putw(w, stream)
       FILE *stream;

Description
       The routine appends the character c to the named output stream.	It returns the character written.

       The routine is defined as (c, stdout).

       The routine behaves like but is a genuine function rather than a macro.

       The routine appends word (that is, int) w to the output stream.	It returns zero.  The routine neither assumes nor causes special alignment
       in the file.

Restrictions
       Because it is implemented as a macro, treats a stream argument with side effects incorrectly.  In particular, `putc(c, *f++);' doesn't work
       as expected.

Diagnostics
       The and functions return the constant EOF upon error.  The function returns a non-zero value on error.

NAME

       putc, putchar, fputc, putw - put character or word on a stream

SYNOPSIS

       #include <stdio.h>

       int putc(c, stream)
       char c;
       FILE *stream;

       putchar(c)

       fputc(c, stream)
       FILE *stream;

       putw(w, stream)
       FILE *stream;

DESCRIPTION

       Putc appends the character c to the named output stream.  It returns the character written.

       Putchar(c) is defined as putc(c, stdout).

       Fputc behaves like putc, but is a genuine function rather than a macro.	It may be used to save on object text.

       Putw  appends  word (i.e.  int) w to the output stream.	It returns the word written.  Putw neither assumes nor causes special alignment in
       the file.

       The standard stream stdout is normally buffered if and only if the output does not refer to a terminal; this default may be changed by set-
       buf(3).	 The  standard	stream	stderr is by default unbuffered unconditionally, but use of freopen (see fopen(3)) will cause it to become
       buffered; setbuf, again, will set the state to whatever is desired.  When an output stream is unbuffered information appears on the  desti-
       nation  file  or  terminal  as  soon  as  written;  when  it  is buffered many characters are saved up and written as a block.  Fflush (see
       fclose(3)) may be used to force the block out early.

SEE ALSO

       fopen(3), fclose(3), getc(3), puts(3), printf(3), fread(3)

DIAGNOSTICS

       These functions return the constant EOF upon error.  Since this is a good integer, ferror(3) should be used to detect putw errors.

BUGS

       Because it is implemented as a macro, putc treats a stream argument with side effects improperly.  In particular `putc(c,  *f++);'  doesn't
       work sensibly.
