module_Lookup()

void* module_Lookup	(	module_handle_t	handle,
		const char *	psz_function
	)

Looks up a symbol from a dynamically loaded library.

This function queries a loaded library for a symbol specified in a string, and returns a pointer to it. We don't check for dlerror() or similar functions, since we want a non-NULL symbol anyway.

Parameters

handle	handle to the module
psz_function	function name

Returns

NULL on error, or the address of the symbol

module_Unload()

void module_Unload

(

module_handle_t

handle

)

CloseModule: unload a dynamic library.

This function unloads a previously opened dynamically linked library using a system dependent method. No return value is taken in consideration, since some libraries sometimes refuse to close properly.

Parameters

handle

handle of the library

Returns

nothing
