40 .Nd create an error message file by massaging C source
49 utility creates a file containing error messages extracted from C source,
50 and restructures the same C source, to utilize the created error message
54 was to reduce the size of large programs and
61 utility processes each of the specified files,
62 placing a restructured version of the input in a file whose name
63 consists of the specified
65 and the original name.
70 .Dl "mkstr pistrings xx *.c"
72 This command causes all the error messages from the C source
73 files in the current directory to be placed in the file
75 and restructured copies of the sources to be placed in
76 files whose names are prefixed with
80 .Bl -tag -width indent
82 Error messages are placed at the end of the specified
83 message file for recompiling part of a large
90 utility finds error messages in the source by
91 searching for the string
94 Each time it occurs, the C string starting at the
97 in the message file followed by a null character and a new-line character;
98 The new source is restructured with
100 pointers into the error message file for retrieval.
101 .Bd -literal -offset indent
102 char efilname = "/usr/lib/pi_strings";
105 error(a1, a2, a3, a4)
110 efil = open(efilname, 0);
112 err(1, "%s", efilname);
114 if (lseek(efil, (off_t)a1, SEEK_SET) < 0 ||
115 read(efil, buf, 256) <= 0)
116 err(1, "%s", efilname);
117 printf(buf, a2, a3, a4);
132 utility was intended for the limited architecture of the PDP 11 family.
133 Very few programs actually use it.
134 The memory savings are negligible in modern computers.
