Detailed Description

These functions add diagnostic tracing to the generated code to assist in finding where a problem might occur. Calls to these macros and functions are added when the -trace command-line argument is used. The diagnostic message can be turned on and off at both C compile and run-time. To C compile the diagnostics in, the _TRACE macro must be defined (-D_TRACE). To turn the diagnostics on at run-time, the rtxSetDiag function must be invoked with the value argument set to TRUE.

Function Documentation

◆ rtxDiagEnabled()

OSBOOL rtxDiagEnabled ( OSCTXT * pctxt )

This function is used to determine if diagnostic tracing is currently enabled for the specified context. It returns true if enabled, false otherwise.

Parameters

pctxt Pointer to context structure.

Returns: Boolean result.

◆ rtxDiagHexDump()

void rtxDiagHexDump	(	OSCTXT *	pctxt,
		const OSOCTET *	data,
		size_t	numocts
	)

This function is used to print a diagnostics hex dump of a section of memory.

Parameters

pctxt	Pointer to context structure.
data	Start address of memory to dump.
numocts	Number of bytes to dump.

◆ rtxDiagPrint()

void rtxDiagPrint	(	OSCTXT *	pctxt,
		const char *	fmtspec,
			...
	)

This function is used to print a diagnostics message to stdout. Its parameter specification is similar to that of the C runtime printf method. The fmtspec argument may contain % style modifiers into which variable arguments are substituted. This function is called in the generated code via the RTDIAG macros to allow diagnostic trace call to easily be compiled out of the object code.

Parameters

pctxt	Pointer to context structure.
fmtspec	A printf-like format specification string describing the message to be printed (for example, "string %s, ivalue %d\n"). A special character sequence (~L) may be used at the beginning of the string to select a trace level (L would be replaced with E for Error, W for warning, I for info, or D for debug).
...	Variable list of parameters to be substituted into the format string.

◆ rtxDiagPrintChars()

void rtxDiagPrintChars	(	OSCTXT *	pctxt,
		const char *	data,
		size_t	nchars
	)

This function is used to print a given number of characters to standard output. The buffer containing the characters does not need to be null-terminated.

Parameters

pctxt	Pointer to context structure.
data	Start address of character string.
nchars	Number of characters to dump (this assumes 1-byte chars).

◆ rtxDiagSetTraceLevel()

void rtxDiagSetTraceLevel	(	OSCTXT *	pctxt,
		OSRTDiagTraceLevel	level
	)

This function is used to set the maximum trace level for diagnostic trace messages. Values are ERROR, WARNING, INFO, or DEBUG. The special string start sequence (~L) described in rtxDiagPrint function documentation is used to set a message level to be compared with the trace level.

Parameters

pctxt	Pointer to context structure.
level	Trace level to be set.

◆ rtxDiagStream()

void rtxDiagStream	(	OSCTXT *	pctxt,
		const char *	fmtspec,
			...
	)

This function conditionally outputs diagnostic trace messages to an output stream defined within the context. A code generator embeds calls to this function into the generated source code when the -trace option is specified on the command line (note: it may embed the macro version of these calls - RTDIAGSTREAMx - so that these calls can be compiled out of the final code.

◆ rtxDiagStreamHexDump()

void rtxDiagStreamHexDump	(	OSCTXT *	pctxt,
		const OSOCTET *	data,
		size_t	numocts
	)

◆ rtxDiagStreamPrintBits()

void rtxDiagStreamPrintBits	(	OSCTXT *	pctxt,
		const char *	descr,
		const OSOCTET *	data,
		size_t	bitIndex,
		size_t	nbits
	)

This function is used to print a given number of bits as '1' or '0' values to a print stream.

Parameters

pctxt	Pointer to context structure.
descr	Descriptive text to print before bits
data	Start address of binary data.
bitIndex	Zero-based offset to first bit to be printed

		const char *	data,
		size_t	nchars
	)

This function is used to print a given number of characters to a print stream. The buffer containing the characters does not need to be null-terminated.

Parameters

pctxt	Pointer to context structure.
data	Start address of character string.
nchars	Number of characters to dump (this assumes 1-byte chars).

◆ rtxDiagToStream()

int rtxDiagToStream	(	OSCTXT *	pctxt,
		const char *	fmtspec,
		va_list	arglist
	)

Diagnostics print-to-stream function. This is the same as the rtxPrintToStream function except that it checks if diagnostic tracing is enabled before invoking the callback function.

Parameters

pctxt	Pointer to context to be used.
fmtspec	A printf-like format specification string describing the message to be printed (for example, "string %s, ivalue %d\n").
arglist	A variable list of arguments passed as va_list

Returns: Completion status, 0 on success, negative value on failure

◆ rtxDiagTraceLevelEnabled()

OSBOOL rtxDiagTraceLevelEnabled	(	OSCTXT *	pctxt,
		OSRTDiagTraceLevel	level
	)

This function tests if a given trace level is enabled.

Parameters

pctxt	Pointer to context structure.
level	Trace level to check.

Returns: True if enabled.

◆ rtxPrintStreamRelease()

int rtxPrintStreamRelease ( OSCTXT * pctxt )

This function releases the memory held by PrintStream in the context

Parameters

pctxt Pointer to a context for which the memory has to be released.

Returns: Completion status, 0 on success, negative value on failure

◆ rtxPrintStreamToFileCB()

void rtxPrintStreamToFileCB	(	void *	pPrntStrmInfo,
		const char *	fmtspec,
		va_list	arglist
	)

Standard callback function for use with print-to-stream for writing to a file.

Parameters

pPrntStrmInfo	User-defined information for use by the callback function. This is supplied by the user at the time the callback is registered. This parameter should be set to the file pointer (FILE*) to which data is to be written.
fmtspec	Format specification of the data to be printed. This is supplied by the print-to-stream utility.
arglist	Variable argument list. This is supplied by the print-to-stream utility.

◆ rtxPrintStreamToStdoutCB()

void rtxPrintStreamToStdoutCB	(	void *	pPrntStrmInfo,
		const char *	fmtspec,
		va_list	arglist
	)

Standard callback function for use with print-to-stream for writing to stdout.

Parameters

pPrntStrmInfo	User-defined information for use by the callback function. This is supplied by the user at the time the callback is registered. In this case, no user-defined information is required, so the argument can be set to NULL when the callback is registered.
fmtspec	Format specification of the data to be printed. This is supplied by the print-to-stream utility.
arglist	Variable argument list. This is supplied by the print-to-stream utility.

◆ rtxPrintStreamToStringCB()

void rtxPrintStreamToStringCB	(	void *	pPrntStrmInfo,
		const char *	fmtspec,
		va_list	arglist
	)

Standard callback function for use with print-to-stream for writing to a string.

Parameters

pPrntStrmInfo	User-defined information for use by the callback function. This is supplied by the user at the time the callback is registered. This parameter should be set to a pointer to an OSRTStrBuf structure.
fmtspec	Format specification of the data to be printed. This is supplied by the print-to-stream utility.
arglist	Variable argument list. This is supplied by the print-to-stream utility.

◆ rtxPrintToStream()

int rtxPrintToStream	(	OSCTXT *	pctxt,
		const char *	fmtspec,
			...
	)

Print-to-stream function which in turn calls the user registered callback function of the context for printing. If no callback function is registered it prints to standard output by default.

Parameters

pctxt	Pointer to context to be used.
fmtspec	A printf-like format specification string describing the message to be printed (for example, "string %s, ivalue %d\n").
...	A variable list of arguments.

Returns: Completion status, 0 on success, negative value on failure

◆ rtxSetDiag()

OSBOOL rtxSetDiag	(	OSCTXT *	pctxt,
		OSBOOL	value
	)

This function is used to turn diagnostic tracing on or off at run-time on a per-context basis. Code generated using ASN1C or XBinder or a similar code generator must use the -trace command line option to enable diagnostic messages. The generated code must then be C compiled with _TRACE defined for the code to be present.

Parameters

pctxt	Pointer to context structure.
value	Boolean switch: TRUE turns tracing on, FALSE off.

Returns: Prior setting of the diagnostic trace switch in the context.

Referenced by OSRTContext::setDiag().

◆ rtxSetGlobalDiag()

OSBOOL rtxSetGlobalDiag ( OSBOOL value )

This function is used to turn diagnostic tracing on or off at run-time on a global basis. It is similar to rtxSetDiag except tracing is enabled within all contexts.

Parameters

value Boolean switch: TRUE turns tracing on, FALSE off.

Returns: Prior setting of the diagnostic trace switch in the context.

◆ rtxSetGlobalPrintStream()

int rtxSetGlobalPrintStream	(	rtxPrintCallback	myCallback,
		void *	pStrmInfo
	)

This function is for setting the callback function for a PrintStream. This version of the function sets a callback at the global level.

Parameters

myCallback	Pointer to a callback print function.
pStrmInfo	Pointer to user defined PrintInfo structure where users can store information required by the callback function across calls. Ex. An open File handle for callbak function which directs stream to a file.

Returns: Completion status, 0 on success, negative value on failure

◆ rtxSetPrintStream()

int rtxSetPrintStream	(	OSCTXT *	pctxt,
		rtxPrintCallback	myCallback,
		void *	pStrmInfo
	)

This function is for setting the callback function for a PrintStream. Once a callback function is set, then all print and debug output ia sent to the defined callback function.
