NAME

	strerror -- map an error number to an error message string

SYNOPSIS

	#include <string.h>

	char *strerror (int errnum)

DESCRIPTION

	Returns a pointer to a string containing an error message, the
	contents of which are implementation defined.  The implementation
	shall behave as if no library function calls strerror.  The string
	pointed to shall not be modified by the caller and is only guaranteed
	to be valid until a subsequent call to strerror.
	
BUGS

	Requires that the system have sys_errlist and sys_nerr.
