Macro Definition Documentation

#define LE_SECSTORE_MAX_ITEM_SIZE   8192

#define LE_SECSTORE_MAX_NAME_SIZE   255

Maximum number of characters and byte storage size permitted for a secure storage item name.

Typedef Documentation

typedef void(* le_secStore_DisconnectHandler_t) (void *)

Type for handler called when a server disconnects.

Function Documentation

void le_secStore_ConnectService ( void  )

Connect the current client thread to the service providing this API. Block until the service is available.

For each thread that wants to use this API, either ConnectService or TryConnectService must be called before any other functions in this API. Normally, ConnectService is automatically called for the main thread, but not for any other thread. For details, see Client-specific Functions.

This function is created automatically.

le_result_t le_secStore_Delete ( const char *LE_NONNULL  name)

Deletes an item from secure storage. If the item name is not valid, this function will kill the calling client.

Returns
LE_OK if successful. LE_NOT_FOUND if the item doesn't exist. LE_UNAVAILABLE if the secure storage is currently unavailable. LE_FAULT if there was some other error.
Parameters
[in]nameName of the secure storage item.
void le_secStore_DisconnectService ( void  )

Disconnect the current client thread from the service providing this API.

Normally, this function doesn't need to be called. After this function is called, there's no longer a connection to the service, and the functions in this API can't be used. For details, see Client-specific Functions.

This function is created automatically.

le_result_t le_secStore_Read ( const char *LE_NONNULL  name,
uint8_t *  bufPtr,
size_t *  bufSizePtr 
)

Reads an item from secure storage. If the item name is not valid or the buffer is NULL, this function will kill the calling client.

Returns
LE_OK if successful. LE_OVERFLOW if the buffer is too small to hold the entire item. No data will be written to the buffer in this case. LE_NOT_FOUND if the item doesn't exist. LE_UNAVAILABLE if the secure storage is currently unavailable. LE_FAULT if there was some other error.
Parameters
[in]nameName of the secure storage item.
[out]bufPtrBuffer to store the data in.
[in,out]bufSizePtr
void le_secStore_SetServerDisconnectHandler ( le_secStore_DisconnectHandler_t  disconnectHandler,
void *  contextPtr 
)

Set handler called when server disconnection is detected.

When a server connection is lost, call this handler then exit with LE_FATAL. If a program wants to continue without exiting, it should call longjmp() from inside the handler.

le_result_t le_secStore_TryConnectService ( void  )

Try to connect the current client thread to the service providing this API. Return with an error if the service is not available.

For each thread that wants to use this API, either ConnectService or TryConnectService must be called before any other functions in this API. Normally, ConnectService is automatically called for the main thread, but not for any other thread. For details, see Client-specific Functions.

This function is created automatically.

Returns
  • LE_OK if the client connected successfully to the service.
  • LE_UNAVAILABLE if the server is not currently offering the service to which the client is bound.
  • LE_NOT_PERMITTED if the client interface is not bound to any service (doesn't have a binding).
  • LE_COMM_ERROR if the Service Directory cannot be reached.
le_result_t le_secStore_Write ( const char *LE_NONNULL  name,
const uint8_t *  bufPtr,
size_t  bufSize 
)

Writes an item to secure storage. If the item already exists, it'll be overwritten with the new value. If the item doesn't already exist, it'll be created. If the item name is not valid or the buffer is NULL, this function will kill the calling client.

Returns
LE_OK if successful. LE_NO_MEMORY if there isn't enough memory to store the item. LE_UNAVAILABLE if the secure storage is currently unavailable. LE_FAULT if there was some other error.
Parameters
[in]nameName of the secure storage item.
[in]bufPtrBuffer containing the data to store.
[in]bufSize
