* 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.
