*
|
|
* Description:
|
|
* This function unloads the object from memory. This essentially undoes
|
|
* the actions of nxflat_load. It is called only under certain error
|
|
* conditions after the module has been loaded but not yet started.
|
|
*
|
|
* Returned Value:
|
|
* 0 (OK) is returned on success and a negated errno is returned on
|
|
* failure.
