37 .Nd create an error message file by massaging C source
46 utility creates files containing error messages extracted from C source,
47 and restructures the same C source, to utilize the created error message
51 was to reduce the size of large programs and
58 utility processes each of the specified
60 placing a restructured version of the input in a file whose name
61 consists of the specified
63 and the original name.
67 .Bd -literal -offset indent
68 mkstr pistrings xx *.c
71 This command causes all the error messages from the C source
72 files in the current directory to be placed in the file
74 and restructured copies of the sources to be placed in
75 files whose names are prefixed with
79 .Bl -tag -width indent
81 Error messages are placed at the end of the specified
82 message file for recompiling part of a large
89 utility finds error messages in the source by
90 searching for the string
93 Each time it occurs, the C string starting at the
96 in the message file followed by a null character and a new-line character;
97 The new source is restructured with
99 pointers into the error message file for retrieval.
100 .Bd -literal -offset indent
101 char efilname = "/usr/lib/pi_strings";
104 error(a1, a2, a3, a4)
109 efil = open(efilname, 0);
111 err(1, "%s", efilname);
113 if (lseek(efil, (off_t)a1, SEEK_SET) < 0 ||
114 read(efil, buf, 256) <= 0)
115 err(1, "%s", efilname);
116 printf(buf, a2, a3, a4);
130 utility was intended for the limited architecture of the PDP 11 family.
131 Very few programs actually use it.
132 The Pascal interpreter,
136 are two programs that are built this way.
137 It is not an efficient method, the error messages
138 should be stored in the program text.
