* as the destination. We save ourselves the copy and are ready

|
* to append the other files to it. If this isn't the first
|
|
* file, * we have already messed up the contents of the source
|
|
* from previous concatenations, so we report that but keep
|
|
* going. If we are doing a touch, go ahead and do it and
|
|
* increment the file counter.

* As an example, suppose the files a.tmp, b.tmp, c.tmp, and

* above would: copy a.tmp to a.out, append b.tmp and b.foo

* into b.out, and copy c.tmp to c.out. The default mode when

|
* doing this type of copy is ascii, so all the .out files would

Routine Description:
|
|
|
|
This routine takes a source filename, an editing pattern, and produces
|
|
an output name suitable for rename or copy. It relies on the semantics
|
|
of ? and * matching. There are a whole raft of user-model issues here
|
|
especially when doing things like:
|
|
|
|
rename *.foo.bar *
|
|
|
|
Does the user intend that the destination * match precisely what the
|
|
source * matches? This is a huge RATHOLE.
|
|
|
|
Arguments:
|
|
|
|
pSrc
|
|
Input filename as produced by find-first/next
|
|
|
|
pEd
|
|
Editing string, containing *, ? and other characters
|
|
|
|
pRes
|
|
Output buffer where edited string is placed
|
|
|
|
ResBufLen
|
|
Length of output buffer
