NAME
       compile_et - error table	compiler

SYNOPSIS
       compile_et file

DESCRIPTION
       Compile_et  converts  a	table  listing error-code names	and associated
       messages	into a C source	file suitable  for  use	 with  the  com_err(3)
       library.

       The  source  file name must end with a suffix of	``.et''; the file con-
       sists of	a declaration supplying	the name (up to	four characters	 long)
       of the error-code table:

       error_table name

       followed	by up to 256 entries of	the form:

       error_code name,	" string "

       and a final

       end

       to indicate the end of the table.

       The  name  of  the  table is used to construct the name of a subroutine
       initialize_XXXX_error_table which must  be  called  in  order  for  the
       com_err library to recognize the	error table.

       The  various  error  codes defined are assigned sequentially increasing
       numbers (starting with a	large number computed as a  hash  function  of
       the name	of the table); thus for	compatibility it is suggested that new
       codes be	added only to the end of an existing table, and	that no	 codes
       be removed from tables.

       The  names  defined  in	the table are placed into a C header file with
       preprocessor directives defining	them as	integer	constants of up	to  32
       bits in magnitude.

       A  C  source file is also generated which should	be compiled and	linked
       with the	object files which reference these error  codes;  it  contains
       the  text  of  the  messages and	the initialization subroutine.	Both C
       files have names	derived	from that of the original  source  file,  with
       the ``.et'' suffix replaced by ``.c'' and ``.h''.

       A  ``#''	 in the	source file is treated as a comment character, and all
       remaining text to the end of the	source line will be ignored.

BUGS
       Since compile_et	uses a very simple parser based	on yacc(1), its	 error
       recovery	leaves much to be desired.

SEE ALSO
