* Name: binfmt_exit
|
|
*
|
|
* Description:
|
|
* This function may be called when a tasked loaded into RAM exits.
|
|
* This function will unload the module when the task exits and reclaim
|
|
* all resources used by the module.
|
|
*
|
|
* Input Parameters:
|
|
* bin - This structure must have been allocated with kmm_malloc() and must
|
|
* persist until the task unloads
|
|
*
|
|
* Returned Value:
|
|
* This is a NuttX internal function so it follows the convention that
|
|
* 0 (OK) is returned on success and a negated errno is returned on
|
|
* failure.
