   13  * @page c_kernelModule Linux Kernel Module API
   14  *
   15  * @ref le_kernelModule_interface.h "API Reference"
   16  *
   17  * This API provides a way for applications to manually load and unload modules that were bundled
   18  * with their system.
   19  *
   20  * Module dependencies and running module load scripts are handled automatically.  Only the name of
   21  * the module in question is required.
   22  *
   23  * To load a module, call @c le_kernelModule_Load.  Unloading is similarly handled by
   24  * @c le_kernelModule_Unload
   25  *
   26  * An example for loading a module:
   27  *
   28  * @code
   29  * le_result_t result = le_kernelModule_Load(moduleName);
   30  *
   31  * LE_FATAL_IF(result != LE_OK, "Could not load the required module, %s.", moduleName);
   32  *
   33  * LE_INFO("Module, %s has been loaded.", moduleName);
   34  * @endcode
