Re: How does one get the description of an errno value

Angel,

The following code snippet should do it.  It basically sets errno
manually and outputs the associated error message.

--- BEGIN ---

#define _ALL_SOURCE

#include <stdio.h>
#include <errno.h> /* for _MAX_ERRNO */

int main(void) {
	int i;
	extern int errno;
	
	for (i = 0; i < MAX_ERRNO; i++) {
		fprintf(stderr, "%3d", i);
		errno = i;
		perror(" ");
	}
	
	return (0);
}

--- END ---

	\Steve
