Linux 2.6 - man page for compile_et (linux section 1)

COMPILE_ET(1)									    COMPILE_ET(1)

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 consists 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  initial-
       ize_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  com-
       patibility  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  direc-
       tives 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 ini-
       tialization  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 the original compile_et uses a very simple parser based on yacc(1), and this current
       version of compile_et uses an awk/sed combination of scripts, its  error  recovery  leaves
       much to be desired.
