38  *
39  *		 1.) fcntl(2) returns...(See Description)
40  *
41  *    INPUT SPECIFICATIONS
42  *		 The standard options for system call tests are accepted.
43  *		 (See the parse_opts(3) man page).
44  *
45  *    OUTPUT SPECIFICATIONS
46  *
47  *    DURATION
48  *		 Terminates - with frequency and infinite modes.
49  *
50  *    SIGNALS
51  *		 Uses SIGUSR1 to pause before test if option set.
52  *		 (See the parse_opts(3) man page).
53  *
54  *    RESOURCES
55  *		 None
56  *
57  *    ENVIRONMENTAL NEEDS
58  *      No run-time environmental needs.

63  *    INTERCASE DEPENDENCIES
64  *		 None
65  *
66  *    DETAILED DESCRIPTION
67  *		 This is a Phase I test for the fcntl(2) system call.  It is intended
68  *		 to provide a limited exposure of the system call, for now.  It
69  *		 should/will be extended when full functional tests are written for
70  *		 fcntl(2).
71  *
72  *		 Setup:
73  *		   Setup signal handling.
74  *		   Pause for SIGUSR1 if option specified.
75  *
76  *		 Test:
77  *		  Loop if the proper options are given.
78  *		   Execute system call
79  *		   Check return code, if system call failed (return=-1)
80  *				 Log the errno and Issue a FAIL message.
81  *		   Otherwise, Issue a PASS message.
82  *
83  *		 Cleanup:
84  *		   Print errno log and/or timing stats if options given
85  *
