Creates a client handle for memory-based ONC RPC for simple
    testing and timing.
    Format
      #include  <rpc/rpc.h>
      CLIENT  *clntraw_create(u_long prognum, u_long versnum);

1  –  Arguments

 prognum
    The program number associated with the remote program.
 versnum
    The version number associated with the remote program.

2  –  Description

    Creates an in-program ONC RPC client for the remote program
    prognum, version versnum. The transport used to pass messages
    to the service is actually a buffer within the process's address
    space, so the corresponding server should live in the same
    address space; see svcraw_create. This allows simulation of
    and acquisition of ONC RPC overheads, such as round-trip times,
    without any kernel interference.

3  –  Return Values

    CLIENT *           A pointer to a client handle.
    NULL               Indicates failure.
