|
.Nd create an error message file by massaging C source
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl
|
|
.Ar messagefile
|
|
.Ar prefix file ...
|
|
.Sh DESCRIPTION
|
|
.Nm Mkstr
|
|
creates files containing error messages extracted from C source,
|
|
and restructures the same C source, to utilize the created error message
|
|
file.
|
|
The intent of
|
|
.Nm
|
|
was to reduce the size of large programs and
|
|
reduce swapping (see
|
|
.Sx BUGS
|
|
section below).
|
|
.Pp
|
|
.Nm Mkstr
|
|
processes each of the specified
|
|
.Ar files ,
|
|
placing a restructured version of the input in a file whose name
|
|
consists of the specified
|
|
.Ar prefix
|
|
and the original name.
|
|
A typical usage of
|
|
.Nm
|
|
is
|
|
.Bd -literal -offset indent
|
|
mkstr pistrings xx *.c
|
|
.Ed
|
|
.Pp
|
|
This command causes all the error messages from the C source
|
|
files in the current directory to be placed in the file
|
|
.Ar pistrings
|
|
and restructured copies of the sources to be placed in
|
|
files whose names are prefixed with
|
|
.Ar \&xx .
|
|
.Pp
|
|
Options:
|
|
.Bl -tag -width indent
|
|
.It Fl
|
|
Error messages are placed at the end of the specified
|
|
message file for recompiling part of a large
|
|
.Nm
|
|
ed
|
|
program.
|
|
.El
|
|
.Pp
|
|
.Nm
|
|
finds error messages in the source by
|
|
searching for the string
|
|
.Li \&`error("'
|
|
in the input stream.
|
|
Each time it occurs, the C string starting at the
|
|
.Sq \&"\&
|
|
is stored
|
|
in the message file followed by a null character and a new-line character;
|
|
The new source is restructured with
|
|
.Xr lseek 2
|
|
pointers into the error message file for retrieval.
|
|
.Bd -literal -offset indent
|
|
char efilname = "/usr/lib/pi_strings";
|
|
int efil = -1;
|
|
|
|
error(a1, a2, a3, a4)
|
|
\&{
|
|
char buf[256];
|
|
|
|
if (efil < 0) {
|
|
efil = open(efilname, 0);
|
|
if (efil < 0) {
|
|
oops:
|
|
perror(efilname);
|
|
exit 1 ;
|
|
}
|
|
}
|
|
if (lseek(efil, (long) a1, 0) \ read(efil, buf, 256) <= 0)
|
|
goto oops;
|
|
printf(buf, a2, a3, a4);

.Nm Mkstr

appeared in

|
|
.Sh BUGS
|
|
.Nm
|
|
was intended for the limited architecture of the PDP 11 family.
|
|
Very few programs actually use it. The Pascal interpreter,
|
|
.Xr \&pi 1
|
|
and the editor,
|
|
.Xr \&ex 1
|
|
are two programs that are built this way.
|
|
It is not an efficient method, the error messages
|
|
should be stored in the program text.
