gmodulecloseGModule

gmodulecloseGModule is a function within the GLib library that is used to unload a dynamically loaded module. When a module is loaded using g_module_open, it reserves resources and occupies memory. gmodulecloseGModule allows developers to release these resources and free up memory when the module is no longer needed.

The function takes a pointer to a GModule structure, which represents the loaded module, as its argument. Upon successful execution, gmodulecloseGModule will decrement the module's reference count. If the reference count reaches zero, the module's shared object is unloaded from the process's address space. This means that any functions or data defined within that module will no longer be accessible.

It is important to use gmodulecloseGModule responsibly. Unloading a module that is still in use can lead to crashes or undefined behavior. Developers should ensure that all references to the module's contents have been cleared before attempting to close it. The function returns TRUE if the module was successfully closed, and FALSE otherwise. Errors might occur if the provided GModule pointer is invalid or if the module cannot be unloaded for some reason. Properly managing the lifecycle of dynamically loaded modules with g_module_open and gmodulecloseGModule is crucial for efficient memory usage and application stability.
