- * NAME
- * getpgid01.c
- *
- * DESCRIPTION
- * Testcase to check the basic functionality of getpgid().
- *
- * ALGORITHM
- * block1: Does getpgid(0), and checks for error.
- * block2: Does getpgid(getpid()) and checks for error.
- * block3: Does getpgid(getppid()) and checks for error.
- * block4: Verifies that getpgid(getpgid(0)) == getpgid(0).
- * block5: Does getpgid(1) and checks for error.

- * USAGE
- * getpgid01
- *
- * HISTORY
- * 07/2001 Ported by Wayne Boyer
- *
- * RESTRICTIONS
- * Expects that there are no EPERM limitations on getting the
- * process group ID from proc 1 (init).
+ * Verify the basic functionality of getpgid(2) syscall.
