DESCRIPTION

mkstr processes each of the specified files, placing a restructured version of the input in a file whose name consists of the specified prefix and the original name. A typical usage of mkstr is

$ mkstr pistrings xx *.c

This command causes all the error messages from the C source files in the current directory to be placed in the file “pistrings” and restructured copies of the sources to be placed in files whose names are prefixed with “xx”.

The options are as follows:

-

Error messages are placed at the end of the specified messagefile for recompiling part of a large mkstred program.

mkstr finds error messages in the source by searching for the string `error("' in the input stream. Each time it occurs, the C string starting at the ‘"’ is stored in the message file followed by a null character and a newline character. The new source is restructured with lseek(2) pointers into the error message file for retrieval.

char efilname = "/usr/lib/pi_strings";
int efil = -1;

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

	if (efil < 0) {
		efil = open(efilname, 0);
		if (efil < 0) {
oops:
			perror(efilname);
			exit 1 ;
		}
	}
	if (lseek(efil, (long) a1, 0)  read(efil, buf, 256) <= 0)
		goto oops;
	printf(buf, a2, a3, a4);
}
