MKSTR(1)MKSTR(1)NAMEmkstr - create an error message file by massaging C source
SYNOPSISmkstr [ - ] messagefile prefix file ...
DESCRIPTION
Mkstr 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.
Mkstr will process each of the specified files, placing a massaged
version of the input file in a file whose name consists of the specified
prefix and the original name.
To process the error messages in the source to the message file mkstr
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 new-line character and a null character; the null character terminates
the message so it can be easily used when retrieved, the new-line
character makes it possible to sensibly cat the error message file to see
its contents. The massaged copy of the input file then contains an
lseek(2) pointer into the file which can be used to retrieve the message,
i.e.:
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);
}
The optional - causes the error messages to be placed at the end of the
specified message file for recompiling part of a large mkstred program.

MKSTR(1)MKSTR(1)EXAMPLE
If the current directory has files "a.c" and "b.c", then
mkstr exs x *.c
would create a new file "exs" which holds all the error messages
extracted from the source files "a.c" and "b.c", as well as two new
source files "xa.c" and "xb.c" which no longer contains the extracted
error messages.
SEE ALSOlseek(2).
BUGS
All the arguments except the name of the file to be processed are
unnecessary.
