The libdl library comprises the APIs that provide the user with the functionality to dynamically load the dynamic link libraries (DLLs) into the address space of the current process , access the addresses of the symbols defined within the loaded DLLs, unload the DLLs (currently loaded) from the address space, and to retrieve the information about the errors that occurred during any of the previous libdl operations. The library thus allows the users to access the services of the loader through a well-defined interface.
