* Name: modhandle
*
* Description:
* modhandle() returns the module handle for the installed module with the
* provided name. A secondary use of this function is to determine if a
* module has been loaded or not.
*
* Input Parameters:
* name - A pointer to the module name string.
*
* Returned Value:
* The non-NULL module handle previously returned by insmod() is returned
* on success. If no module with that name is installed, modhandle() will
* return a NULL handle and the errno variable will be set appropriately.
*
