man dlopen
man dlsym
short example:
typedef int (*func_t)(char *, int);
void handle;
func_t func;
handle = dlopen("/usr/local/lib/libfoo.so", RTLD_LAZY);
if (handle == NULL)
errx(1, "%s", dlerror());
func = (func_t)dlsym(handle, "foofunction");
if (func == NULL)
errx(1, "%s", dlerror());
func("bar", 1000);
dlclose(handle);
