| * 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. |
