Arguments

 

nodename

   OpenVMS usage:char_string
   type:         character string
   access:       read only
   mechanism:    by descriptor

   Node name to be compressed. The nodename argument contains the
   address of a descriptor pointing to this node-name string.

   The error LIB$_INVARG is returned if nodename contains an invalid
   node name, points to a null string, or contains more than 1024
   characters. The error LIB$_INVSTRDES is returned if the nodename
   descriptor is invalid.
 

compressed-nodename

   OpenVMS usage:char_string
   type:         character string
   access:       write only
   mechanism:    by descriptor

   Compressed node name. The compressed-nodename argument contains
   the address of a descriptor pointing to the compressed node-name
   string. LIB$COMPRESS_NODENAME writes the compressed node name
   into the buffer pointed to by compressed-nodename.

   The error LIB$_INVSTRDES is returned if compressed-nodename is an
   invalid descriptor.

   The length field of the compressed-nodename descriptor is not
   updated unless compressed-nodename is a dynamic descriptor with a
   length less than the resulting compressed node name. Refer to the
   OpenVMS RTL String Manipulation (STR$) Manual for dynamic string
   descriptor usage.

   The compressed-nodename argument contains an unusable result when
   LIB$COMPRESS_NODENAME returns in error.
 

resultant-length

   OpenVMS usage:word_unsigned
   type:         word (unsigned)
   access:       write only
   mechanism:    by reference

   Length of the compressed node name. The resultant-length argument
   is the address of an unsigned word that contains this length in
   bytes.

   The resultant-length argument contains an unusable result when
   LIB$COMPRESS_NODENAME returns in error.
