# Finding Partitions Example
This example demonstrates how to use the partition API functions `esp_partition_find` and `esp_partition_find_first` to search the device partition table.
These functions return the matching partitions given a set of constraints. By constraints we simply mean
properties that returned results should match - notably partition type, subtype and label/name. In the case of `esp_partition_find_first`, the first matching instance is returned;
properties that returned results should match - notably partition type, subtype and label/name. In the case of `esp_partition_find_first`, the first matching instance is returned;
for `esp_partition_find`, an iterator is returned iterating over matching instances.

The example uses a [custom partition table](./partitions_example.csv). The first part uses `esp_partition_find_first` to search for partition instances

using two constraints - type and subtype. However, the partition table contains partitions with same type/subtype combination. In order to differentiate these partitions,
a third constraint - the label, is specified.
The second part shows how to iterate over partitions that match certain constraints, manually checking the properties of each iterated partition.

The iterator is obtained using `esp_partition_find` and is released after its use to avoid memory leaks.

# Partition Read, Write, Erase Example

The example uses a [custom partition table](./partitions_example.csv), with a data partition `storage` used as the demo partition. For the most part the example code is well-commented so users should be able to follow along the code easily. Nevertheless, this section provides an overview of the code flow.
The partition table is searched for the `storage` partition. Once found, the entire partition is erased using `esp_partition_erase_range`. Sample data is written using `esp_partition_write`
and read back using `esp_partition_read`, verifying the read and written data match. The partition is erased once again using `esp_partition_erase_range`, limited to the sector the sample data was written to.
