       mkstr - create an error message file

       mkstr [-] messagefile prefix file...

       The  command  is	 used  to create files of error messages.  Its use can
       make programs with large numbers of error diagnostics much smaller, and
       reduce  system overhead in running the program as the error messages do
       not have to be constantly swapped in and out.

       The command will process each of the specified files,  placing  a  mas‐
       saged  version  of  the input file in a file whose name consists of the
       specified prefix and the original name.	A typical usage of would be:
       mkstr pistrings xx *.c
       This command would cause all the error messages from the C source files
       in  the	current	 directory to be placed in the file pistrings and pro‐
       cessed copies of the source for these files to be placed in files whose
       names are prefixed with xx.

       To process the error messages in the source to the message file keys on
       the string `error("' in the input stream.  Each time it occurs,	the  C
       string  starting at the `"' is placed in the message file followed by a
       null character and a new-line character.	 The null character terminates
       the message so it can be easily used when retrieved, the new-line char‐
       acter makes it possible to sensibly the error message file to  see  its
       contents.   The massaged copy of the input file then contains a pointer
       into the file which can be used to retrieve the message, that is:
       char filename[] =  "/usr/lib/pi_strings";
       int  file = -1;

       error(a1, a2, a3, a4)
	    char buf[256];

	    Bif (efil < 0) {
		 efil = open(efilname, 0);
		 if (efil < 0) {
	    if (lseek(efil, (long) a1, 0) || read(efil, buf, 256) <= 0)
		 goto oops;
	    printf(buf, a2, a3, a4);

       -  Places error messages at the end of specified message file.
