Arguments

 

buffer

   OpenVMS usage:address
   type:         longword (unsigned)
   access:       read/write
   mechanism:    by 32- or 64-bit reference
   The user buffer in which the alignment fault data is to be
   stored. The buffer argument is the 32- or 64-bit virtual address
   of this buffer.
 

buffer_size

   OpenVMS usage:byte count
   type:         longword (signed)
   access:       read
   mechanism:    by value
   The size, in bytes, of the buffer specified by the buffer
   argument.
 

return_size

   OpenVMS usage:longword_signed
   type:         longword (signed)
   access:       write
   mechanism:    by 32- or 64-bit reference
   The amount of data, in bytes, stored in the buffer. The return_
   size argument is the 32- or 64-bit virtual address of a naturally
   aligned longword into which the service returns the amount of
   data, in bytes, stored in the buffer. The return_size argument is
   set to 0 if there is no data in the buffer.
