NAME

6       mkstr - create an error message file by massaging C source files
7

SYNOPSIS

9       /usr/ucb/mkstr [-] messagefile prefix filename...
10
11

DESCRIPTION

13       The mkstr utility creates files of error messages. You can use mkstr to
14       make programs with large numbers of error diagnostics much smaller, and
15       to  reduce  system  overhead in running the program — as the error mes‐
16       sages do not have to be constantly swapped in and out.
17
18
19       mkstr processes each of the specified  filenames,  placing  a  massaged
20       version of the input file in a file with a name consisting of the spec‐
21       ified prefix and the original source file name. A  typical  example  of
22       using mkstr would be:
23
24         mkstr pistrings processed *.c
25
26
27
28
29       This command would cause all the error messages from the C source files
30       in the current directory to be placed in the file  pistrings  and  pro‐
31       cessed copies of the source for these files to be placed in files whose
32       names are prefixed with processed.
33
34
35       To process the error messages in the source to the message file,  mkstr
36       keys  on the string `error("' in the input stream. Each time it occurs,
37       the C string starting at the `"' is placed in the message file followed
38       by  a null character and a NEWLINE character; the null character termi‐
39       nates the message so it can be easily used when retrieved, the  NEWLINE
40       character  makes  it possible to sensibly cat the error message file to
41       see its contents. The massaged copy of the input file then  contains  a
42       lseek  pointer into the file which can be used to retrieve the message,
43       that is:
44
45              char efilname[] = "/usr/lib/pi_strings";
46              int efil = −1;
47
48              error(a1, a2, a3, a4)
49              {
50
51                   char
52                   buf[256];
53                   if (efil < 0) {
54
55                                efil = open(efilname, 0);
56                                if (efil < 0) {
57         oops:
58                                perror (efilname);
59                                exit (1);
60                   }
61              }
62              if (lseek(efil, (long) a1, 0) || read(efil, buf, 256) <= 0)
63                   goto oops;
64              printf(buf, a2, a3, a4);
65         }

OPTIONS

69       −       Place error messages at the end of the specified  message  file
70               for recompiling part of a large mkstred program.
