[Freeswitch-dev] quick question about the following lines of code
in file switch_loadable_module.c: switch_loadable_module_load_file(char *path, char *filename, switch_bool_t global, switch_loadable_module_t **new_module) #ifdef WIN32 dso = switch_dso_open("FreeSwitch.dll", load_global, &derr); #elif defined (MACOSX) || defined(DARWIN) dso = switch_dso_open(SWITCH_PREFIX_DIR "/lib/libfreeswitch.dylib", load_global, &derr); #else dso = switch_dso_open(NULL, load_global, &derr); #endif why the else case is dso open "NULL"? shouldn't it be lib/libfreeswitch.so?

Looks cleaner this way to me. Read the man page for dlopen(). If NULL is provided, the handle for the main program will be returned and dlsym() will look into the main program and libraries loaded at startup for the symbol.
