Arguments

 

code_base_va

   OpenVMS usage: address
   type:          quadword (unsigned)
   access:        read only
   mechanism:     by value
   With code_size, defines the potential code range. code_base_va
   is required for both creation and extension calls. code_base_va
   is the process virtual address of the start of the code region.
   code_size is the size of the code region in bytes. An error is
   returned if this overlaps any existing range.
 

code_size

   OpenVMS usage: address
   type:          quadword (unsigned)
   access:        read only
   mechanism:     by value
   With code_base_va, defines the potential code range. code_base_va
   is required for both creation and extension calls. code_base_va
   is the process virtual address of the start of the code region.
   code_size is the size of the code region in bytes. An error is
   returned if this overlaps any existing range.
 

ut_base_va

   OpenVMS usage: address
   type:          quadword (unsigned)
   access:        read only
   mechanism:     by value
   With ut_size, describes the unwind table (UT). ut_base_va is the
   process virtual address of the UT and must be quadword aligned.
   ut_size is the size of the UT in bytes and must be a multiple of
   the size (24 bytes: 3 quadwords) of an unwind table entry (UTE).
   The UTEs must describe nonoverlapping code subregions within the
   overall code region.
 

ut_size

   OpenVMS usage: address
   type:          quadword (unsigned)
   access:        read only
   mechanism:     by value
   With ut_base_va, describes the unwind table (UT). ut_base_va
   is the process virtual address of the UT and must be quadword
   aligned. ut_size is the size of the UT in bytes and must be
   a multiple of the size (24 bytes: 3 quadwords) of an unwind
   table entry (UTE). The UTEs must describe nonoverlapping code
   sub regions within the overall code region.
 

gp_value

   OpenVMS usage: address
   type:          quadword (unsigned)
   access:        read only
   mechanism:     by value
   Ignored on extension calls, required on create calls. The Global
   Data Pointer (GP) value for the routines described by these
   unwind tables.
 

unwind_info_base

   OpenVMS usage: address
   type:          quadword (unsigned)
   access:        read only
   mechanism:     by value
   Ignored on extension calls; required on create calls. The unwind_
   info_base plus a particular UTE UIB offset must add up to the
   process virtual address of that UIB. Typically for static
   code (activated images from disk), this specifies the process
   virtual base address of the segment containing the UIBs. However,
   dynamically generated code, for example, can pass a zero for the
   unwind_info_base and have the full process virtual addresses of
   the UIBs in their UTEs.
 

name

   OpenVMS usage: pseudo-image-name
   type:          character-code-text-string
   access:        read only
   mechanism:     by descriptor-fixed-length string descriptor
   Passed by descriptor (ignored on extension calls). May be used
   for traceback. Need not be unique. Should be less than 255
   characters (will be truncated, otherwise).
