62  * 	1.) gethostname(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).
67  *
68  *    DURATION
69  * 	Terminates - with frequency and infinite modes.
70  *
71  *    SIGNALS
72  * 	Uses SIGUSR1 to pause before test if option set.
73  * 	(See the parse_opts(3) man page).

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