environment variables - Problems with using setenv and then making the dlopen call -

i using setenv set dyld_library_path when dlopen() have right paths find .dylib, when dlopen() doesn't seem search paths added dyld_library_path.

from can gather changes dyld_library_path won't take effect until re-execute process happens. correct?

also if correct, there way set dyld_library_path , having changes work out doing reset of process.

oh yeah writing code on mac osx.

thanks in advance.

i don't know mac os, on linux, loader reads value of getenv("ld_library_path") once, , saves away, long before first instruction of executable runs. subsequent modification of ld_library_path programme affects children execve()s, not process itself. imagine it's similar on mac os.

the usual way around either re-execve proces (java this), or utilize shell wrapper sets environment , exec's real binary (firefox that).

there might mac os specific way update library search path, though google doesn't seem find matches. pretty sure there isn't such mechanism on linux.
