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. SEE ALSO
