Arguments

 

pc

   OpenVMS usage: PC value
   type:          quadword (unsigned)
   access:        read only
   mechanism:     by value
   Input quadword, target PC (that is, the PC for a code region the
   user wants unwind information for).
 

get_ue_block

   OpenVMS usage: unwind_entry_data_block
   type:          quadword (unsigned)
   access:        write
   mechanism:     by reference
   Address of a 4-quadword block to be filled in. That is, input the
   address of a 4 quadword block and, on successful returned status,
   that block will be updated with the following information:

   o  code_start_va - Output quadword, the process virtual starting
      c unwind region containing the input IP.

   o  code_end_va - Output quadward, the process virtual ending code
      address of the unwind region containing the input IP.

   o  uib_start_va - Output quadword, the process virtual address of
      the UIB for the unwind region containing the input IP.

   o  gp_value - Output quadword, the GP value for this code region.
 

name

   OpenVMS usage: pseudo-image-name
   type:          character-code-text-string
   access:        modify
   mechanism:     by descriptor-fixed-length string descriptor
   Optional, that is, may be zero. If the name parameter is
   specified and if a name was registered for the unwind region,
   then the descriptor pointer and length are updated to point to
   that stored name. Note that if the name parameter is specified
   but no name exists in the unwind tables, then the name descriptor
   is updated to zero length.
