/*
|
|
* mkstr - create a string error message file by massaging C source
|
|
*
|
|
* Bill Joy UCB August 1977
|
|
*
|
|
* Modified March 1978 to hash old messages to be able to recompile
|
|
* without addding messages to the message file (usually)
|
|
*
|
|
* Based on an earlier program conceived by Bill Joy and Chuck Haley
|
|
*
|
|
* Program to create a string error message file
|
|
* from a group of C programs. Arguments are the name
|
|
* of the file where the strings are to be placed, the
|
|
* prefix of the new files where the processed source text
|
|
* is to be placed, and the files to be processed.
|
|
*
|
|
* The program looks for 'error("' in the source stream.
|
|
* Whenever it finds this, the following characters from the '"'
|
|
* to a '"' are replaced by 'seekpt' where seekpt is a
|
|
* pointer into the error message file.
|
|
* If the '(' is not immediately followed by a '"' no change occurs.
|
|
*
|
|
* The optional '-' causes strings to be added at the end of the
|
|
* existing error message file for recompilation of single routines.
