Arguments

 

context

   OpenVMS usage:context
   type:         longword (unsigned)
   access:       write only
   mechanism:    by reference
   Value identifying the data stream that DCX$MAKE_MAP maps. The
   context argument is the address of a longword containing this
   value. DCX$ANALYZE_INIT initializes this value; you should not
   modify it. You can define multiple context arguments to identify
   multiple data streams that are processed simultaneously.
 

map_addr

   OpenVMS usage:address
   type:         longword (unsigned)
   access:       write only
   mechanism:    by reference
   Starting address of the compression/expansion function. The map_
   addr argument is the address of a longword into which DCX$MAKE_
   MAP stores the virtual address of the compression/expansion
   function.
 

map_size

   OpenVMS usage:longword_signed
   type:         longword (unsigned)
   access:       write only
   mechanism:    by reference
   Length of the compression/expansion function. The map_size
   argument is the address of the longword into which DCX$MAKE_MAP
   writes the length of the compression/expansion function.
