+** File: nameshm1.c -- Test Named Shared Memory
+**
+** Description: 
+** nameshm1 tests Named Shared Memory. nameshm1 performs two tests of
+** named shared memory. 
+** 
+** The first test is a basic test. The basic test operates as a single
+** process. The process exercises all the API elements of the facility.
+** This test also attempts to write to all locations in the shared
+** memory.
+**
+** The second test is a client-server test. The client-server test
+** creates a new instance of nameshm1, passing the -C argument to the
+** new process; this creates the client-side process. The server-side
+** (the instance of nameshm1 created from the command line) and the
+** client-side interact via inter-process semaphores to verify that the
+** shared memory segment can be read and written by both sides in a
+** synchronized maner.
+**
+** Note: Because this test runs in two processes, the log files created
+** by the test are not in chronological sequence; makes it hard to read.
+** As a temporary circumvention, I changed the definition(s) of the
+** _PUT_LOG() macro in prlog.c to force a flushall(), or equivalent.
+** This causes the log entries to be emitted in true chronological
+** order.
+**
+** Synopsis: nameshm1 [options] [name]
+** 
+** Options:
+** -d       Enables debug trace via PR_LOG()
+** -v       Enables verbose mode debug trace via PR_LOG()
+** -w       Causes the basic test to attempt to write to the segment
+**          mapped as read-only. When this option is specified, the
+**          test should crash with a seg-fault; this is a destructive
+**          test and is considered successful when it seg-faults.
+** 
+** -C       Causes nameshm1 to start as the client-side of a
+**          client-server pair of processes. Only the instance
+**          of nameshm1 operating as the server-side process should
+**          specify the -C option when creating the client-side process;
+**          the -C option should not be specified at the command line.
+**          The client-side uses the shared memory segment created by
+**          the server-side to communicate with the server-side
+**          process.
+**          
+** -p <n>   Specify the number of iterations the client-server tests
+**          should perform. Default: 1000.
+**
+** -s <n>   Size, in KBytes (1024), of the shared memory segment.
+**          Default: (10 * 1024)
+**
+** -i <n>   Number of client-side iterations. Default: 3
+**
+** name     specifies the name of the shared memory segment to be used.
+**          Default: /tmp/xxxNSPRshm
+**
+**
+** See also: prshm.h
+**
