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 is the 32- or 64-bit address of this user
   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 address of a naturally aligned
   longword into which the service returns the size of the buffer.
   The return_size is set to 0 if there is no data in the buffer.
