NAME

mkstr

 - create an error message file by massaging C source

 

SYNOPSIS

DESCRIPTION

The utility 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 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 ''

Options:

-

Error messages are placed at the end of the specified message file for recompiling part of a large ed program.

The utility 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 new-line 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)
                        err(1, "%s", efilname);
        }
        if (lseek(efil, (off_t)a1, SEEK_SET) < 0 ||
            read(efil, buf, 256) <= 0)
                err(1, "%s", efilname);
        printf(buf, a2, a3, a4);
}
