A "buffPtr" is a pointer to a buffer of data. If your data is in a pascal
string then you could do something like this:

count:=length(mystring);
error:=FSWrite(refNum, count, ptr(ord(@mystring)+1));

In the example above, we are passing the pointer of a string 1 byte passed
the length byte of the string.

If your data is/are in a TERecord then you could do this:

count:=MyTERec^^.teLength;	{set the length of the data}
error:=FSWrite(refNum, count, ptr(MyTERec^^.hText^));

That should write what was in MyTErec in to the file.
