LE_MEM_DEFINE_STATIC_POOL | ( | taf_can_ClientThreadData | , |
LE_CDATA_COMPONENT_COUNT | , | ||
sizeof(_ClientThreadData_t) | |||
) |
Static pool for client threads.
|
static |
Initialize thread specific data, and connect to the service for the current thread.
|
static |
Get a pointer to the client thread data for the current thread.
If the current thread does not have client data, then NULL is returned
__attribute__ | ( | (unused) | ) |
Return the sessionRef for the current thread.
If the current thread does not have a session ref, then this is a fatal error.
|
static |
Destructor function for client thread objects.
|
static |
Init data that is common across all threads.
|
static |
Connect to the service, using either blocking or non-blocking calls.
This function implements the details of the public ConnectService functions.
void taf_can_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 apiFilesC_client.
This function is created automatically.
le_result_t taf_can_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 apiFilesC_client.
This function is created automatically.

static |
void taf_can_SetServerDisconnectHandler | ( | taf_can_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.
|
static |
void taf_can_SetNonExitServerDisconnectHandler | ( | taf_can_DisconnectHandler_t | disconnectHandler, |
void * | contextPtr | ||
) |
Set handler called when server disconnection is detected without exiting.
When a server connection is lost, call this handler without exit.
void taf_can_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 apiFilesC_client.
This function is created automatically.
