Home -> Community -> Mailing Lists -> Oracle-L -> RE: question about DynaLoader::dl_load_file from perl profiler output
IIRC, DynaLoader::dl_load_file looks for and physically loads an object that the perl program is dynamically linked against or calling in some fashion. Then the dl_ calls you see at the bottom handle symbol resolution, etc.
Thanks,
Matt
