Detailed Description

Legato Secure Storage Admin API

Macro Definition Documentation

#define SECSTOREADMIN_MAX_PATH_SIZE   511

Maximum number of characters and byte storage size permitted for a path.

Typedef Documentation

typedef void(* secStoreAdmin_DisconnectHandler_t) (void *)

Type for handler called when a server disconnects.

typedef struct secStoreAdmin_Iter* secStoreAdmin_IterRef_t

Iterator to list entries in secure storage.

Function Documentation

void secStoreAdmin_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 secStoreAdmin_CopyMetaTo ( const char *LE_NONNULL  path)

Copy the meta file to the specified path.

Returns
LE_OK if successful. LE_NOT_FOUND if the meta file does not exist. LE_UNAVAILABLE if the sfs is currently unavailable. LE_FAULT if there was some other error.
Parameters
[in]pathDestination path of meta file copy.
secStoreAdmin_IterRef_t secStoreAdmin_CreateIter ( const char *LE_NONNULL  path)

Create an iterator for listing entries in secure storage under the specified path.

Returns
An iterator reference if successful. NULL if the secure storage is currently unavailable.
Parameters
[in]pathPath to iterate over.
le_result_t secStoreAdmin_Delete ( const char *LE_NONNULL  path)

Recursively deletes all items under the specified path and the specified path from secure storage.

Note
The specified path must be an absolute path.
Returns
LE_OK if successful. LE_NOT_FOUND if the path doesn't exist. LE_UNAVAILABLE if the secure storage is currently unavailable. LE_FAULT if there was some other error.
Parameters
[in]pathPath of the secure storage item.
void secStoreAdmin_DeleteIter ( secStoreAdmin_IterRef_t  iterRef)

Deletes an iterator.

Parameters
[in]iterRefIterator reference.
void secStoreAdmin_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 secStoreAdmin_GetEntry ( secStoreAdmin_IterRef_t  iterRef,
char *  name,
size_t  nameSize,
bool *  isDirPtr 
)

Get the current entry's name.

Returns
LE_OK if successful. LE_OVERFLOW if the buffer is too small to hold the entry name. LE_UNAVAILABLE if the secure storage is currently unavailable.
Parameters
[in]iterRefIterator reference.
[out]nameBuffer to store the entry name.
[in]nameSize
[out]isDirPtrTrue if the entry is a directory, false otherwise.
le_result_t secStoreAdmin_GetSize ( const char *LE_NONNULL  path,
uint64_t *  sizePtr 
)

Gets the size, in bytes, of all items under the specified path.

Note
The specified path must be an absolute path.
Returns
LE_OK if successful. LE_NOT_FOUND if the path doesn't exist. LE_UNAVAILABLE if the secure storage is currently unavailable. LE_FAULT if there was some other error.
Parameters
[in]pathPath of the secure storage item.
[out]sizePtrSize in bytes of all items in the path.
le_result_t secStoreAdmin_GetTotalSpace ( uint64_t *  totalSizePtr,
uint64_t *  freeSizePtr 
)

Gets the total space and the available free space in secure storage.

Returns
LE_OK if successful. LE_UNAVAILABLE if the secure storage is currently unavailable. LE_FAULT if there was some other error.
Parameters
[out]totalSizePtrTotal size, in bytes, of secure storage.
[out]freeSizePtrFree space, in bytes, in secure storage.
le_result_t secStoreAdmin_Next ( secStoreAdmin_IterRef_t  iterRef)

Go to the next entry in the iterator. This should be called at least once before accessing the entry. After the first time this function is called successfully on an iterator the first entry will be available.

Returns
LE_OK if successful. LE_NOT_FOUND if there are no more entries available.
Parameters
[in]iterRefIterator reference.
le_result_t secStoreAdmin_Read ( const char *LE_NONNULL  path,
uint8_t *  bufPtr,
size_t *  bufSizePtr 
)

Reads an item from secure storage.

Note
The specified path must be an absolute path.
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]pathPath of the secure storage item.
[out]bufPtrBuffer to store the data in.
[in,out]bufSizePtr
void secStoreAdmin_SetServerDisconnectHandler ( secStoreAdmin_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 secStoreAdmin_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 secStoreAdmin_Write ( const char *LE_NONNULL  path,
const uint8_t *  bufPtr,
size_t  bufSize 
)

Writes a buffer of data into the specified path in 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.

Note
The specified path must be an absolute path.
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]pathPath of the secure storage item.
[in]bufPtrBuffer containing the data to store.
[in]bufSize
