This location must be + pre-allocated by the caller. + + +Returns +~~~~~~~ + +If successful, returns a non-``NULL`` pointer to the found symbol, and +stores a pointer to the library in which it was found at the location +pointed to by lib. + +If the symbol could not be found, returns ``NULL``. + + +Description +----------- + +This function finds the specified symbol in one of the currently loaded +libraries. It returns the address of the symbol. Upon return, the +location pointed to by the parameter lib contains a pointer to the +library that contains that symbol. The location must be pre-allocated by +the caller. + +The function returns ``NULL`` if no such function can be found. The +order in which the known libraries are searched in not specified. This +function is equivalent to calling first :ref:`PR_LoadLibrary`, then +:ref:`PR_FindSymbol`. + +The identity returned from this function must be the target of a +:ref:`PR_UnloadLibrary` in order to return the runtime to its original +state. |
