+ * Test Name: mmap02
+ *
+ * Test Description:
+ *  Call mmap() with prot parameter set to PROT_READ and with the file
+ *  descriptor being open for read, to  map a file creating mapped memory
+ *  with read access. The minimum file permissions should be 0444.
+ *
+ *  The call should succeed to create the mapped region with required
+ *  attributes.
+ *
+ * Expected Result:
+ *  mmap() should succeed returning the address of the mapped region,
+ *  the mapped region should contain the contents of the mapped file.
+ *
+ * Algorithm:
+ *  Setup:
+ *   Setup signal handling.
+ *   Pause for SIGUSR1 if option specified.
+ *   Create temporary directory.
+ *
+ *  Test:
+ *   Loop if the proper options are given.
+ *   Execute system call
+ *   Check return code, if system call failed (return=-1)
+ *   	Log the errno and Issue a FAIL message.
+ *   Otherwise,
+ *   	Verify the Functionality of system call	
+ *      if successful,
+ *      	Issue Functionality-Pass message.
+ *      Otherwise,
+ *		Issue Functionality-Fail message.
+ *  Cleanup:
+ *   Print timing stats if options given
+ *   Delete the temporary directory created.
+ *
+ * Usage:  <for command-line>
+ *  mmap02 [-c n] [-f] [-i n] [-I x] [-P x] [-t]
+ *     where,  -c n : Run n copies concurrently.
+ *             -f   : Turn off functionality Testing.
+ *	       -i n : Execute test n times.
+ *	       -I x : Execute test for x seconds.
+ *	       -P x : Pause for x seconds between iterations.
+ *	       -t   : Turn on syscall timing.
+ *
+ * HISTORY
+ *	07/2001 Ported by Wayne Boyer
+ *
+ * RESTRICTIONS:
+ *  None.
