Description

LibSharedMemoryObject provides a simple API to load from memory shared library on both Linux (.so) and Windows (.dll).

API

Example of use of API without error handling for sake of simplicity.

smo_handle *handle;
typedef void(*hello_world_func)(void);
hello_world_func hello_world;

/* Where buffer and size are the content of your memory library */
handle = smo_open("your_id", buffer, size);

/**
 * hello world is now a ptr of the function hello_world()
 * located in the memory library
 */
hello_world = smo_get_function(handle, "hello_world");

/* Print the hello world message from library */
hello_world();

smo_close(handle);

And that's all you need !
