File: threadsup.c

Description:

    This file provides initialization of the ExportTable structure. Glock
    can't handle this initialization in threads.cxx, so we do it here
    and define the table as extern in threads.cxx.

History:
  2/14/92 [davidst] file created
  5/10/94 [vonj]    Added I_RpcRegisteredBufferAllocate and
                    I_RpcRegisteredBufferFree exports.  This change
                    allows the Microsoft Exchange DOS Client's
                    Shell-to-DOS function to recognize SPX-registered
                    buffers and avoid swapping them.
