Subject use of UDF in DLL on WinXP
Author marcdecaluwe

I had a piece of software running with Apache-PHP-Firebird 1.0.3 that
uses some UDF's in DLL's. Everything worked fine on Win98.
I installed it on WinXP, and everything is ok with one exception: the
UDF's don't work anymore.
I get errors like: "invalid request BLR at offset 73 function BLOBSIZE
is not defined module name or entrypoint could not be found" (BLOBSIZE
is a function in the DLL).
The DLL itself seems to be on the right place. I don't have much
experience with XP, but is it possible maybe that permissions are not
set right or something alike?

Thanks for your help!
