Path of library / GetModuleHandle() equivalent

[Logodae]

I'm in the process of porting a Windows plugin to the Mac, and I'm looking for the equivalent of GetModuleHandle(). Basically, I need to be able to get the path of the plugin, which is a dynamically linked library, at runtime. If anyone could point me in the right direction, I'd appreciate it.

CFBundleCopyBundleURL

Okay, but on what?

My original solution was to use CFBundleGetMainBundle() and then CFBundleCopyBundleURL(), but that only gets me the application path, not the plugin path...

Edit: CFBundleGetBundleWithIdentifier() looks promising...

Edit2: Or not. A library isn't actually a bundle, I suspect.

Thanks anyway.

What kind of a library? You can use CFBundleGetBundleWithIdentifier to get the system frameworks, and CFBundleCreate + CFBundleLoadExecutable to load a plug-in. CFBundleCopyBundleURL is the function you want.

Oh, I see -- your code is the plug-in, loaded by some host application you have no control over.

Hmm.

How is your plug-in structured? You make it sound as if it's a "naked" executable file, which would be odd for a native Mac app...

This kind of works:

main.c:

#include <dlfcn.h>

int main(int argc, const char *argv[]) {
void *handle = dlopen("test.bundle", RTLD_LAZY);
void (*test)(void) = dlsym(handle, "test");
test();
dlclose(handle);
return 0;
}


test.c:

#include <stdio.h>
#include <dlfcn.h>

void test(void) {
Dl_info info;
int result = dladdr(test, &info);

printf("dladdr returns %d; gives %s\n",
result,
info.dli_fname);
}


gcc main.c
gcc -bundle test.c -o test.bundle
./a.out

But it returns the path that the plug-in was loaded with (in this case, a relative one).
