36  *		 1.) fcntl(2) returns...(See Description)
37  *
38  *    INPUT SPECIFICATIONS
39  *		 The standard options for system call tests are accepted.
40  *		 (See the parse_opts(3) man page).

43  *
44  *    DURATION
45  *		 Terminates - with frequency and infinite modes.
46  *
47  *    SIGNALS
48  *		 Uses SIGUSR1 to pause before test if option set.
49  *		 (See the parse_opts(3) man page).

63  *    DETAILED DESCRIPTION
64  *		 This is a Phase I test for the fcntl(2) system call.  It is intended
65  *		 to provide a limited exposure of the system call, for now.  It
66  *		 should/will be extended when full functional tests are written for
67  *		 fcntl(2).
68  *
69  *		 Setup:
70  *		   Setup signal handling.
71  *		   Pause for SIGUSR1 if option specified.
72  *
73  *		 Test:
74  *		  Loop if the proper options are given.
75  *		   Execute system call
76  *		   Check return code, if system call failed (return=-1)
77  *				 Log the errno and Issue a FAIL message.
78  *		   Otherwise, Issue a PASS message.
79  *
80  *		 Cleanup:
81  *		   Print errno log and/or timing stats if options given
82  *
