Greetings,
~ if (!orig_fopen)
~ orig_fopen = dlsym(RTLD_NEXT, "fopen");
~
~ should do what you want. (RTLD_NEXT isn't documented in the dlsym
~ manpage, just in <dlfcn.h>, which says
~
~ /* If the first argument of `dlsym' is set to RTLD_NEXT the run-time
~ address of the symbol called NAME in the next shared object is
~ returned. The "next" relation is defined by the order the shared
~ objects were loaded. */
~ #define RTLD_NEXT ((void *) -1l)
~ )
~
so If I would load say 3 libraries ahead, which would have the same
routines defined, I will get them in back-order the libraries were loaded,
by calling dlsym(RTLD_NEXT,"routine") 3 times. Sounds neat to me. Thanks
for the hints.
