Arguments

 

number-of-bytes

   OpenVMS usage:quadword_signed
   type:         quadword integer (signed)
   access:       read only
   mechanism:    by reference

   Number of contiguous bytes to be deallocated by LIB$FREE_VM_64.
   The number-of-bytes argument is the address of a signed quadword
   integer that contains this number. The value of number-of-bytes
   must be greater than zero.

   Byte counts are rounded in the same manner as in LIB$GET_VM_64.

                                  NOTE

      You may omit the number-of-bytes argument if you are using
      boundary tags (LIB$M_VM_BOUNDARY_TAGS).
 

base-address

   OpenVMS usage:address
   type:         quadword (unsigned)
   access:       read only
   mechanism:    by reference

   Address of the first byte to be deallocated by LIB$FREE_VM_64.
   The base-address argument contains the address of an unsigned
   quadword that is this address. The value of base-address must be
   the address of a block of memory that was allocated by a previous
   call to LIB$GET_VM_64.
 

zone-id

   OpenVMS usage:identifier
   type:         quadword (unsigned)
   access:       read only
   mechanism:    by reference

   The address of a quadword that contains a zone identifier created
   by a previous call to LIB$CREATE_VM_ZONE_64 or LIB$CREATE_USER_
   VM_ZONE_64.

   You must specify the same zone-id value as when you called
   LIB$GET_VM_64 to allocate the block. An error status will
   be returned if you specify an incorrect zone-id. The zone-id
   argument is optional. If zone-id is omitted or if the quadword
   contains the value 0, the 64-bit default zone is used.
