- * 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
- * 0 (OK) is returned on success and a negated errno is returned on
- * failure.
