Function Documentation
void le_appInfo_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.
void le_appInfo_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_appInfo_GetHash | ( | const char * | appName, |
char * | hashStr, | ||
size_t | hashStrNumElements | ||
) |
Gets the application hash as a hexidecimal string. The application hash is a unique hash of the current version of the application.
- Returns
- LE_OK if the application has was successfully retrieved. LE_OVERFLOW if the application hash could not fit in the provided buffer. LE_NOT_FOUND if the application is not installed. LE_FAULT if there was an error.
- Parameters
-
[in] appName Application name. [out] hashStr Hash string. [in] hashStrNumElements
le_result_t le_appInfo_GetName | ( | int32_t | pid, |
char * | appName, | ||
size_t | appNameNumElements | ||
) |
Gets the application name of the process with the specified PID.
- Returns
- LE_OK if the application name was successfully found. LE_OVERFLOW if the application name could not fit in the provided buffer. LE_NOT_FOUND if the process is not part of an application. LE_FAULT if there was an error.
- Parameters
-
[in] pid PID of the process. [out] appName Application name. [in] appNameNumElements
le_appInfo_ProcState_t le_appInfo_GetProcState | ( | const char * | appName, |
const char * | procName | ||
) |
Gets the state of the specified process in an application. This function only works for configured processes that the Supervisor starts directly.
- Returns
- The state of the specified process.
- Parameters
-
[in] appName Application name. [in] procName Process name.
le_appInfo_State_t le_appInfo_GetState | ( | const char * | appName | ) |
Gets the state of the specified application. The state of unknown applications is STOPPED.
- Returns
- The state of the specified application.
- Parameters
-
[in] appName Application name.
le_result_t le_appInfo_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.
