gmoduleclose

Gmoduleclose is a function in the GNU C Library (glibc) that is used to close a dynamically loaded module. This function is part of the dynamic linking interface provided by glibc, which allows programs to load and unload shared libraries at runtime. The gmoduleclose function takes a single argument, which is a pointer to the module handle returned by the gmoduleopen function. When gmoduleclose is called, it unloads the specified module from memory and releases any resources associated with it. This function is useful in scenarios where a program needs to dynamically load and unload modules based on runtime conditions, such as plugins or extensions. It is important to note that gmoduleclose should only be called after all references to the module have been released, as unloading a module while it is still in use can lead to undefined behavior. Additionally, gmoduleclose does not unload the module if it is still referenced by other parts of the program, ensuring that the module remains loaded until all references are released.
