    NAME

    
    
    mkstr
    
     - create an error message file by massaging C source
    
     
    

    SYNOPSIS

    [- ] mesgfile prefix file ...  

    DESCRIPTION

    The utility creates a file containing error messages extracted from C source, and restructures the same C source, to utilize the created error message file. The intent of was to reduce the size of large programs and reduce swapping (see Sx BUGS section below).

    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);
    }

    HISTORY

    An utility appeared in BSD 3.0  

    BUGS

    The utility was intended for the limited architecture of the PDP 11 family. Very few programs actually use it. The memory savings are negligible in modern computers.
