   6: **  INGRES ERROR MESSAGE GENERATOR
   7: **
   8: **	Error message `num' is sent up towards process 1 with param-
   9: **	eters `msg'.  This routine may have any number of parameters,
  10: **	but the last one must be zero.
  11: **
  12: **	In process one, the appropriate error file is scanned for the
  13: **	actual message.  The parameters are then substituted into that
  14: **	message.  If the error message doesn't exist, then the first
  15: **	parameter is printed as is.
  16: **
  17: **	History:
  18: **		1/8/79 (eric) -- Removed temporary code to check for
  19: **			old error numbers; removed 'Err_base'.
  20: **		8/17/78 (rse) -- Removed error offset. Doesn't write
  21: **			if W_err is negative, returns error code instead
  22: **			of -1.
  23: **		9/22/78 (rse) -- Added EXEC_ERROR for exec_id.
