62  * 	1.) unlink(2) returns...(See Description)
63  *
64  *    INPUT SPECIFICATIONS
65  * 	The standard options for system call tests are accepted.
66  *	(See the parse_opts(3) man page).

69  *$
70  *    DURATION
71  * 	Terminates - with frequency and infinite modes.
72  *
73  *    SIGNALS
74  * 	Uses SIGUSR1 to pause before test if option set.
75  * 	(See the parse_opts(3) man page).

89  *    DETAILED DESCRIPTION
90  *	This is a Phase I test for the unlink(2) system call.  It is intended
91  *	to provide a limited exposure of the system call, for now.  It
92  *	should/will be extended when full functional tests are written for
93  *	unlink(2).
94  *
95  * 	Setup:
96  * 	  Setup signal handling.
97  *	  Pause for SIGUSR1 if option specified.
98  *
99  * 	Test:
100  *	 Loop if the proper options are given.
101  * 	  Execute system call
102  *	  Check return code, if system call failed (return=-1)
103  *		Log the errno and Issue a FAIL message.
104  *	  Otherwise, Issue a PASS message.
105  *
106  * 	Cleanup:
107  * 	  Print errno log and/or timing stats if options given
108  *
