- Dynamic Loading of Modules

#### Structs

Module | The `GModule` struct is an opaque data structure to represent a dynamically-loaded module. It should only be accessed via the following functions.

#### Bitfields

ModuleFlags | Flags passed to g_module_open(). Note that these flags are not supported on all platforms.

#### Error Domains

ModuleError | Errors returned by g_module_open_full(). since: 2.70

#### Callbacks

ModuleCheckInit | Specifies the type of the module initialization function. If a module contains a function named `g_module_check_init()` it is called automatically when the module is loaded. It is passed the `GModule` structure and should return `NULL` on success or a string describing the initialization error.
ModuleUnload | Specifies the type of the module function called when it is unloaded. If a module contains a function named `g_module_unload()` it is called automatically when the module is unloaded. It is passed the `GModule` structure.
