+ * File: cancel1.c

+ * Test Synopsis: Test setting cancel state and cancel type.
+ * - 
+ *
+ * Test Method (Validation or Falsification):
+ * - 
+ *
+ * Requirements Tested:
+ * - pthread_setcancelstate function
+ * - pthread_setcanceltype function
+ *
+ * Features Tested:
+ * - 
+ *
+ * Cases Tested:
+ * - 
+ *
+ * Description:
+ * - 
+ *
+ * Environment:
+ * - 
+ *
+ * Input:
+ * - None.
+ *
+ * Output:
+ * - File name, Line number, and failed expression on failure.
+ * - No output on success.
+ *
+ * Assumptions:
+ * - pthread_create, pthread_self work.
+ *
+ * Pass Criteria:
+ * - Process returns zero exit status.
+ *
+ * Fail Criteria:
+ * - Process returns non-zero exit status.
