NAME
       putc - put a byte on a stream

SYNOPSIS
       #include <stdio.h>

       int putc(int c, FILE *stream);

DESCRIPTION
       The  putc() function shall be equivalent to fputc(), except that if it is implemented as a
       macro it may evaluate stream more than once, so the argument should never be an expression
       with side effects.

RETURN VALUE
       Refer to fputc() .

ERRORS
       Refer to fputc() .

       The following sections are informative.

EXAMPLES
       None.

APPLICATION USAGE
       Since  it  may  be  implemented	as  a macro, putc() may treat a stream argument with side
       effects incorrectly. In particular, putc(c,*f++)  does  not  necessarily  work  correctly.
       Therefore,  use	of this function is not recommended in such situations; fputc() should be
       used instead.

RATIONALE
       None.

FUTURE DIRECTIONS
       None.
