Arguments

 

invo_handle

   OpenVMS usage:invo_handle
   type:         longword (unsigned)
   access:       read only
   mechanism:    by value

   Handle for the invocation to be updated.
 

invo_context

   OpenVMS usage:invo_context_blk
   type:         structure
   access:       read only
   mechanism:    by reference

   Address of an invocation context block that contains the values
   to be written to the registers.

   Each register that is set in the invo_mask parameter is updated
   using the value found in the corresponding IREG or FREG field of
   the invocation context block. The program counter and processor
   status of the given invocation can also be updated in this way.
   No other fields of the invocation context block are used.
 

invo_mask

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

   Address of a 64-bit vector, where each bit corresponds to a
   register field in the passed invo_context. Bits 0 through 29
   correspond to IREG[0] through IREG[29], bit 30 corresponds
   to STACK_POINTER and cannot be changed, bit 31 corresponds to
   PROGRAM_COUNTER, bits 32 through 62 correspond to FREG[0] through
   FREG[30], and bit 63 corresponds to PROCESSOR_STATUS.
