DLFCN(3)              DragonFly Library Functions Manual              DLFCN(3)

NAME

dlopen, fdlopen, dlclose, dlinfo, dladdr, dlsym, dlfunc, dlvsym, dl_iterate_phdr, dlerror -- programmatic interface to the dynamic linker

LIBRARY

This function is not in a library. It is included in every dynamically linked program automatically.

SYNOPSIS

#include <dlfcn.h> void * dlopen(const char *name, int mode); void * fdlopen(int fd, int mode); int dlclose(void *handle); int dlinfo(void * restrict handle, int request, void * restrict p); int dladdr(const void * restrict addr, Dl_info * restrict info); void * dlsym(void * restrict handle, const char * restrict name); dlfunc_t dlfunc(void * restrict handle, const char * restrict name); void * dlvsym(void * restrict handle, const char * restrict name, const char * restrict version); char * dlerror(void); #include <link.h> int dl_iterate_phdr(int (*callback)(struct dl_phdr_info *, size_t, void *), void * data);

DESCRIPTION

These functions provide an interface to the run-time linker ld-elf.so.2(1). They allow new shared objects to be loaded into the process' address space under program control.
