 * Test for checking error conditions for getrlimit(2):
 *
 * 1. getrlimit(2) returns -1 and sets errno to EFAULT if an invalid
 *	  address is given for address parameter.
 * 2. getrlimit(2) returns -1 and sets errno to EINVAL if an invalid
 *	  resource type (RLIM_NLIMITS is a out of range resource type) is
 *	  passed.
