Detailed Description


Typedef Documentation

typedef void(* OSAPI_Log_write_buffer_T)(const char *buffer, RTI_SIZE_T length)

Optional user-defined function to output a log/trace buffer.

The handler is set by OSAPI_Log_set_property().

Parameters:
[in]bufferPointer to buffer with log to write
[in]lengthLength of the buffer to write
typedef void(* OSAPI_LogHandler_T)(void *param, OSAPI_LogEntry_T *entry)

Optional user-defined function for processing new log messages.

Definition of a function that can be installed with the logger and that will be called for each new log event.

The handler is set by OSAPI_Log_set_log_handler().

When called, provides parameters containing the raw log entry and additional optional information.

Parameters:
[in]paramUser-defined payload
[in]msgLog entry
[in]kindKind of log message
[in]ecUnique error code of log message
[in]moduleModule of log message
[in]fileName of source file. Optional.
[in]funcName of function. Optional.
[in]lineLine number. Optional.
[in]argcVariable length argument count
[in]apVariable length argument list

Function Documentation

RTI_BOOL OSAPI_Log_set_log_handler ( OSAPI_LogHandler_T  handler,
void *  param 
)

Install a log handler.

The log functionality allows the user to specify a log handler. The log handler is a function which is called for every logged event. It is up to the user to decide what to do with the log message. The handler is a global function pointer.

Parameters:
[in]handlerPointer to log handler function
[in]paramParameter passed to the log handler function. This parameter is transparent to the log functionality.
Returns:
RTI_TRUE on success, RTI_FALSE on failure
RTI_BOOL OSAPI_Log_get_log_handler ( OSAPI_LogHandler_T handler,
void **  param 
)

Return the current log handler.

Return the current log handler.

Parameters:
[in]handlerPointer to store log handler function
[in]paramPointer to store the current log handler parameter.
Returns:
RTI_TRUE on success, RTI_FALSE on failure
RTI_BOOL OSAPI_Log_set_trace_handler ( OSAPI_TraceHandler_T  handler,
void *  param 
)

Install a trace handler.

Install a custom trace handler. Traces are not stored in the log-buffer and is generally used to analyze behavior interactively. the default trace handler outputs the trace data to a console.

Parameters:
[in]handlerPointer to trace handler function
[in]paramParameter passed to the trace handler function. This parameter is transparent to the trace functionality.
Returns:
RTI_TRUE on success, RTI_FALSE on failure
RTI_BOOL OSAPI_Log_get_trace_handler ( OSAPI_TraceHandler_T *  handler,
void **  param 
)

Return the trace handler.

Return the current trace handler and trace parameter. This information can be used to daisy-chain calls to multiple trace-handlers.

Parameters:
[in]handlerPointer to store trace handler function
[in]paramPointer to store the trace handler parameter.
Returns:
RTI_TRUE on success, RTI_FALSE on failure
RTI_BOOL OSAPI_Log_set_display_handler ( OSAPI_LogDisplay_T  handler,
void *  param 
)

Install a display handler.

The display handler is responsible for outputting log messages to a console.

Parameters:
[in]handlerPointer to display function
[in]paramParameter passed to the display handler function. This parameter is transparent to the log functionality.
Returns:
RTI_TRUE on success, RTI_FALSE on failure
RTI_BOOL OSAPI_Log_get_display_handler ( OSAPI_LogDisplay_T *  handler,
void **  param 
)

Return the current display function.

Return the current log handler.

Parameters:
[in]handlerPointer to store display handler function
[in]paramPointer to store the current display handler parameters.
Returns:
RTI_TRUE on success, RTI_FALSE on failure
void OSAPI_Log_set_verbosity ( OSAPI_LogVerbosity_T  verbosity)

Set the log verbosity.

Change the log verbosity. The new setting takes immediate effect.

Parameters:
[in]verbosityNew log verbosity
void OSAPI_Trace_set_trace_mask ( RTI_UINT32  mask)

Set the trace mask.

Parameters:
[in]maskNew trace mask
RTI_BOOL OSAPI_Log_clear ( void  )

Clear the log buffer.

Clear the log buffer, all the current entries are lost

Returns:
RTI_TRUE on success, RTI_FALSE on failure
RTI_INT32 OSAPI_Log_get_last_error_code ( void  )

Returns the error code for a function that failed.

Many functions returns RTI_FALSE or NULL on failure. In order to provide additional information about reason for the failure fucntions may set an additional error code. This function returns the last error-code recorded for the calling thread.

Returns:
Last error-code recorded for this thread
void OSAPI_Log_get_property ( struct OSAPI_LogProperty property)

Get the current log properties.

Return the current log properties

Parameters:
[out]property- Current log properties
See also:
OSAPI_Log_set_property
RTI_BOOL OSAPI_Log_set_property ( struct OSAPI_LogProperty property)

Set the log properties.

Set the current log properties. It is not possible to set new properties after OSAPI_Log_initialize() has been called/

Parameters:
[in]propertyNew log properties
Returns:
RTI_TRUE if new properties can be set, RTI_FALSE otherwise

OSAPI_Log_get_property
