[gdal-dev] [#3824][RFC] Introduce portable DllMain callback to DLL binary

[Mateusz Loskot]

Hi,

I have proposed implementation of entry and exit points for GDAL shared
library. Initially, it was Windows-specific DllMain callback, but later
I found it may be possible to use GCC extensions implement similar
behaviour for Linux (Unix?) system. Here is the related ticket:

http://trac.osgeo.org/gdal/ticket/3824


The main motivation is to sanitize the run-time environment and
perform all necessary clean-up during GDAL library unload,
so it does not leave any resources (memory) unreleased.

Frank suggested to discuss this idea on the list, so here we go
and I'm looking forward to hearing your comments.

Best regards,
