Function Documentation

void explain_putc_or_die	(	int	c,
		FILE *	fp
	)

The explain_putc_or_die function is used to call the putc(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_putc(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

This function is intended to be used in a fashion similar to the following example:

 explain_putc_or_die(c, fp);

Parameters:

c	The c, exactly as to be passed to the putc(3) system call.
fp	The fp, exactly as to be passed to the putc(3) system call.

Returns:

This function only returns on success. On failure, prints an explanation and exits, it does not return.
