The IBM OS/2 RPC implementation differs from the Sun Microsystems RPC implementation as follows:

• The global variables svc_socks[ ] and noregistered are used in place of the svc_fds global variable. See svc_socks[ ] for the use of these variables.

• Functions that rely on file descriptor structures are not supported.

• The svc_getreq() call supports the socks and noavail global variables. In the Sun Microsystems implementation, the svc_getreq() call supports the rdfds global variable.

• TYPES.H for RPC has been renamed to RPCTYPES.H.
