Arguments

 

context

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

in_rec

   OpenVMS usage:char_string
   type:         character string
   access:       read only
   mechanism:    by descriptor
   Data record to be expanded. The in_rec argument is the address of
   the descriptor of the data record string.
 

out_rec

   OpenVMS usage:char_string
   type:         character string
   access:       write only
   mechanism:    by descriptor
   Data record that has been expanded. The out_rec argument is the
   address of the descriptor of the expanded record returned by
   DCX$EXPAND_DATA.
 

 

out_length

   OpenVMS usage:word_signed
   type:         word integer (signed)
   access:       write only
   mechanism:    by reference
   Length (in bytes) of the expanded data record. The out_length
   argument is the address of a word into which DCX$EXPAND_DATA
   returns the length of the expanded data record.
