Subject: problems with textview_FindLineNumber...

I got the following problem:

After having inserted a certain amount of characters in a textobject I
want to know from the
corresponding textview how many additional lines had to be brought up
therefore.  Here's
in short what I'm doing:

tView is the textview and t the associated textobject, buf is a
char-pointer to the inserted string,
insertPos the insert position and length the strlen(buf):

{
...
oldlines = textview_FindLineNumber(tView,insertPos);
text_AlwaysInsertCharacters(t,insertPos,buf,length);
newlines = textview_FindLineNumber(tView,insertPos+length);

numberOfNewLines = (newlines - oldlines);
...
}

But this doesn't work as textview_FindLineNumber returns (as for my
part!) strange values.
Has anybody got an idea how to get along or perhaps can tell me what
this method really returns?

Thanks in advance,
		Christoph
