The PMAPPROC_CALLIT procedure enables a caller to call another remote procedure on the same machine without knowing the remote procedure's port number. It supports broadcasts to arbitrary remote programs by using the well-known port mapper's port. The parameters prog, vers, proc, and the bytes of args are the program number, version number, procedure number, and parameters of the remote procedure. See also the pmap_rmtcall() function in the rpc_soc(3NSL) man page.

This procedure only sends a response if the procedure was successfully executed and is silent (no response) otherwise. It also returns the remote program's port number, and the bytes of results are the results of the remote procedure.

The port mapper communicates with the remote program using UDP/IP only.
