|
|
*
|
|
* Description:
|
|
* This function may be called to when a task is loaded into memory. It
|
|
* will setup the to automatically unload the module when the task exits.
|
|
*
|
|
* Input Parameters:
|
|
* pid - The task ID of the newly loaded task
|
|
* bininfo - This structure allocated with kmm_malloc(). This memory
|
|
* persists until the task exits and will be used unloads
|
|
* the module from memory.
|
|
*
|
|
* Returned Value:
|
|
* This is a NuttX internal function so it follows the convention that

|
|
* failure.
