hi friends,

bit of background. we are porting a windows application to solaris. In windows they are using dll.

my question is , is there anything equivalent to dllmain() in .so format?

also is there any guide to see how to write a .so in the same way as "beginers guide to dll " in microsoft help?

thanks,
harish

i don't think there's a dllmain, you have to call the function after you run dlopen

I don't know about solaris but linux doesn't support c++ in .so
you may need to wrap your c++ functions with extern "c" functions.

making a .so is just like writing a normal program, except compile it with the -shared option in gcc, and not including a main function of course.
