DLOPEN(3) DLOPEN(3) NAME dlopen, dlsym, dlerror, dlclose - simple programmatic interface to the dynamic linker SYNOPSIS #include <dlfcn.h> void *dlopen(path, mode) const char *path; int mode; void *dlsym(handle, symbol) void *handle; const char *symbol; char *dlerror() int dlclose(handle); void *handle; They used to be around for a long time. I think the shared lib implementation also uses them, basically. Well, the man page source has CVS tags reaching back to FreeBSD 2.0.5. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
