35 .Nd create an error message file by massaging C source
44 utility creates a file containing error messages extracted from C source,
45 and restructures the same C source, to utilize the created error message
49 was to reduce the size of large programs and
56 utility processes each of the specified files,
57 placing a restructured version of the input in a file whose name
58 consists of the specified
60 and the original name.
65 .Dl "mkstr pistrings xx *.c"
67 This command causes all the error messages from the C source
68 files in the current directory to be placed in the file
70 and restructured copies of the sources to be placed in
71 files whose names are prefixed with
75 .Bl -tag -width indent
77 Error messages are placed at the end of the specified
78 message file for recompiling part of a large
85 utility finds error messages in the source by
86 searching for the string
89 Each time it occurs, the C string starting at the
92 in the message file followed by a null character and a new-line character;
93 The new source is restructured with
95 pointers into the error message file for retrieval.
96 .Bd -literal -offset indent
97 char efilname = "/usr/lib/pi_strings";
100 error(a1, a2, a3, a4)
105 efil = open(efilname, 0);
107 err(1, "%s", efilname);
109 if (lseek(efil, (off_t)a1, SEEK_SET) < 0 ||
110 read(efil, buf, 256) <= 0)
111 err(1, "%s", efilname);
112 printf(buf, a2, a3, a4);
122 utility first appeared in
133 utility was intended for the limited architecture of the PDP 11 family.
134 Very few programs actually use it.
135 The memory savings are negligible in modern computers.
