SA_EXPORT int sa_open_data_storage | ( | void | ) |
Prepares the resources needed for retrieving data storage statistics. This function exists (and is needed) only when SA_OPEN_DATA_STORAGE is defined.
SA_EXPORT int sa_close_data_storage | ( | void | ) |
This function closes the resources used for retrieving data storage statistics. You should call it even when there was a previous error in another function of this API. This function exists (and is needed) only when SA_CLOSE_DATA_STORAGE is defined.
SA_EXPORT int sa_count_data_storages | ( | uint16_t * | number | ) |
Gives the total number of data storage devices.
number | The number will be stored here |
SA_EXPORT int sa_get_data_storage | ( | char * | name, | |
struct sa_data_storage * | dst | |||
) |
Retrieves statistics from a data storage device identified by its name.
name | The name of the data storage device. | |
dst | Where the statistics will be stored. |
SA_EXPORT int sa_get_data_storages | ( | struct sa_data_storage * | dst, | |
uint16_t | dst_size, | |||
uint16_t * | written | |||
) |
Retrieves statistics about all the storage devices' activity.
dst | A buffer where the statistics will be stored. | |
dst_size | The number of devices that fits in the dst buffer. If it's not big enough dst will be filled but ENOMEM will be returned. | |
written | The amount of device statistics written. |
