40 .Nd create an error message file by massaging C source
49 utility creates files 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
63 placing a restructured version of the input in a file whose name
64 consists of the specified
66 and the original name.
70 .Bd -literal -offset indent
71 mkstr pistrings xx *.c
74 This command causes all the error messages from the C source
75 files in the current directory to be placed in the file
77 and restructured copies of the sources to be placed in
78 files whose names are prefixed with
82 .Bl -tag -width indent
84 Error messages are placed at the end of the specified
85 message file for recompiling part of a large
92 utility finds error messages in the source by
93 searching for the string
96 Each time it occurs, the C string starting at the
99 in the message file followed by a null character and a new-line character;
100 The new source is restructured with
102 pointers into the error message file for retrieval.
103 .Bd -literal -offset indent
104 char efilname = "/usr/lib/pi_strings";
107 error(a1, a2, a3, a4)
112 efil = open(efilname, 0);
114 err(1, "%s", efilname);
116 if (lseek(efil, (off_t)a1, SEEK_SET) < 0 ||
117 read(efil, buf, 256) <= 0)
118 err(1, "%s", efilname);
119 printf(buf, a2, a3, a4);
134 utility was intended for the limited architecture of the PDP 11 family.
135 Very few programs actually use it.
136 The memory savings are negligible in modern computers.
