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.
