Dynamic Linking & Qnx 4

hello i use an old version of Qnx 4.25 i need to know:
Is it true that Dynamic Linking (dlopen(), dlclose(), dlsym() …) is not supported in this release? This release is
good for my hardware and my process so i can’t upgrade it.
Have you any other solution from your part? Exist an equivalent solution?

thanks a lot

That’s true, these function do not exists.

However through the art of black magic it is possible, there is a document that describes it, not for the faint of heard. I thing the document is on QNX ftp site somewhere.
