strerror() returns a pointer to a null terminated character array containing an error message that corresponds to errnum. Although normally the integer value in errnum will come from the global variable errno, strerror() will provide a message translation for any value of type int.

#include <string.h>
#include <stdio.h>

int main(void)
{
	puts(strerror(8));
	puts(strerror(ESIGPARM));

	return 0;
}
