Functions [#functions]
lv_vector_for_each_destroy_tasks [#lv_vector_for_each_destroy_tasks]
This is the main function to draw the accumulated vector tasks by passing them to a vector renderer callback. When the callback returns the processed vector task will be destroyed.
```c title=" " lineNumbers=1
void lv_vector_for_each_destroy_tasks(lv_ll_t *task_list, vector_draw_task_cb cb, void *used_data)
```
Parameters
| Name | Type | Description |
| ----------- | ---------------------------------------------- | ------------------------------------------------------------------------------------------------------ |
| `task_list` | | pointer to the linked list in `lv_draw_vector_dsc_t` that stores the path shapes and their attributes. |
| `cb` | | the callback used to iterate through the task |
| `used_data` | `void *` | |
Structs [#structs]
\_lv_vector_path_t [#_lv_vector_path_t]
Stores the shape of the path as arrays of operations and points. For example move to 10;20 then draw a line to 30;40 and draw an arc with 30 radius and 70° sweep.
`lv_vector_path_ctx_t` is also required to describe how to fill and stroke the path.
