Typedef Documentation

◆ le_bootReason_DisconnectHandler_t

typedef void(* le_bootReason_DisconnectHandler_t) (void *)

Type for handler called when a server disconnects.

Function Documentation

◆ le_bootReason_ConnectService()

void le_bootReason_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_bootReason_DisconnectService()

void le_bootReason_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_bootReason_SetServerDisconnectHandler()

void le_bootReason_SetServerDisconnectHandler ( le_bootReason_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_bootReason_TryConnectService()

le_result_t le_bootReason_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_bootReason_WasAdc()

bool le_bootReason_WasAdc ( uint32_t  adcNum)

Checks whether boot reason was due to the specified ADC having a reading above or below the configured limits.

Returns
true if boot reason was due to the given ADC or false otherwise.
Note
The process exits if an invalid ADC number is passed. Check corresponding device documents for valid list of ADC numbers.
Parameters
[in]adcNumADC number

◆ le_bootReason_WasGpio()

bool le_bootReason_WasGpio ( uint32_t  gpioNum)

Checks whether boot-reason was specific gpio change. GPIO number is specified in parameter.

Returns
  • TRUE if boot-reason was specified gpio change.
  • FALSE otherwise.
Note
The process exits if invalid gpio number is passed. Check corresponding device documents for valid list of gpio.
Parameters
[in]gpioNumGPIO number.

◆ le_bootReason_WasTimer()

bool le_bootReason_WasTimer ( void  )

Checks whether boot-reason was timer expiry.

Returns
  • TRUE if boot-reason was timer expiry.
  • FALSE otherwise.
