Arguments

 

start_va_64

   OpenVMS usage:address
   type:         quadword address
   access:       read only
   mechanism:    by value
   Lowest address in range of addresses that express the stack's new
   limits. For a memory stack, this address is the stack limit. For
   an Integrity servers register stack, this address is the stack
   base.
 

length_64

   OpenVMS usage:length
   type:         quadword (unsigned)
   access:       read only
   mechanism:    by value
   Length of the range of addresses that express the stack's new
   limits.
 

acmode

   OpenVMS usage:access_mode
   type:         longword (unsigned)
   access:       read only
   mechanism:    by value
   Access mode of the stack to be altered. The acmode argument is
   a longword containing the access mode. The $PSLDEF macro defines
   symbols for the four access modes. The most privileged access
   mode used is the access mode of the caller.

   If acmode specifies user mode, $SETSTK_64 performs no operation
   and returns the SS$_NORMAL condition value.
 

flags

   OpenVMS usage:mask_longword
   type:         longword (unsigned)
   access:       read only
   mechanism:    by value
   0 for memory stack (Alpha and Integrity servers VA$M_SETSTK_
   REGISTER for register stack (Integrity servers only)

   The $VADEF macro and VADEF.H file define symbolic names for the
   flags argument.
 

prev_start_va_64

   OpenVMS usage:address
   type:         quadword address
   access:       write only
   mechanism:    by reference
   Lowest address in the range of addresses that express the stack's
   previous limits. For a memory stack, this address was the stack
   limit. For an Integrity servers register stack, this address was
   the stack base.
 

prev_length_64

   OpenVMS usage:length
   type:         quadword
   access:       write only
   mechanism:    by reference
   Length of the range of addresses that express the stack's
   previous limits.
