nvs_entry_find() function
Create an iterator to enumerate NVS entries based on one or more parameters
{c}
// Example of listing all the key-value pairs of any type under specified partition and namespace
nvs_iterator_t it = NULL;
esp_err_t res = nvs_entry_find(, , NVS_TYPE_ANY, &it);
while(res == ESP_OK) {
nvs_entry_info_t info;
nvs_entry_info(it, &info); // Can omit error check if parameters are guaranteed to be non-NULL
printf("key '%s', type '%d' \n", info.key, info.type);
res = nvs_entry_next(&it);
}
nvs_release_iterator(it);
Syntax

Return value
- ESP_OK if no internal error or programming error occurred. - ESP_ERR_NVS_NOT_FOUND if no element of specified criteria has been found. - ESP_ERR_NO_MEM if memory has been exhausted during allocation of internal structures. - ESP_ERR_INVALID_ARG if any of the parameters is NULL. Note: don't release \c output_iterator in case ESP_ERR_INVALID_ARG has been returned
