mkstr
creates files containing error messages extracted
from C source, and restructures the same C source, to use the created error
message file. The intent of mkstr
was to reduce the
size of large programs and reduce swapping (see
BUGS section below).
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.
Options:
-
mkstr
ed 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 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) { oops: perror(efilname); exit 1 ; } } if (lseek(efil, a1, 0) < 0 || read(efil, buf, 256) ≤ 0) goto oops; printf(buf, a2, a3, a4); }
mkstr
appeared in 1BSD.
mkstr
was intended for the limited architecture of the
PDP-11 family. Very few programs actually use it. It is not an efficient
method, the error messages should be stored in the program text.
