returnValue MessageHandling::throwError	(	returnValue	Enumber,
		const char *	additionaltext,
		const char *	functionname,
		const char *	filename,
		const unsigned long	linenumber,
		VisibilityStatus	localVisibilityStatus
	)

Prints an error message(a simplified macro THROWERROR is also provided).
Errors are definied as abnormal events which cause an immediate termination of the current (sub) function. Errors of a sub function should be commented by the calling function by means of a warning message (if this error does not cause an error of the calling function, either)!

Returns:: Error number returned by sub function call

Parameters:

Enumber	Error number returned by sub function call.
additionaltext	Additional error text (0, if none).
functionname	Name of function which caused the error.
filename	Name of file which caused the error.
linenumber	Number of line which caused the error.incompatible binary file
localVisibilityStatus	Determines (locally) if error message can be printed to stdFile. If GLOBAL visibility status of the message is set to VS_HIDDEN, no message is printed, anyway!

returnValue MessageHandling::throwInfo	(	returnValue	Inumber,
		const char *	additionaltext,
		const char *	functionname,
		const char *	filename,
		const unsigned long	linenumber,
		VisibilityStatus	localVisibilityStatus
	)

Prints a info message (a simplified macro THROWINFO is also provided).

Returns:: Info number returned by sub function call

Parameters:

Inumber	Info number returned by sub function call.
additionaltext	Additional warning text (0, if none).
functionname	Name of function which submitted the info.
filename	Name of file which submitted the info.
linenumber	Number of line which submitted the info.
localVisibilityStatus	Determines (locally) if info message can be printed to stdFile. If GLOBAL visibility status of the message is set to VS_HIDDEN, no message is printed, anyway!

		const char *	functionname,
		const char *	filename,
		const unsigned long	linenumber,
		VisibilityStatus	localVisibilityStatus,
		const char *	RETstring
	)		`[protected]`

Prints a info message to stdFile (auxiliary function).

Returns:: Error/warning/info number returned by sub function call

Parameters:

RETnumber	Error/warning/info number returned by sub function call.
additionaltext	Additional warning text (0, if none).
functionname	Name of function which caused the error/warning/info.
filename	Name of file which caused the error/warning/info.
linenumber	Number of line which caused the error/warning/info.
localVisibilityStatus	Determines (locally) if info message can be printed to stdFile. If GLOBAL visibility status of the message is set to VS_HIDDEN, no message is printed, anyway!
RETstring	Leading string of error/warning/info message.

		const char *	additionaltext,
		const char *	functionname,
		const char *	filename,
		const unsigned long	linenumber,
		VisibilityStatus	localVisibilityStatus
	)

Prints a warning message (a simplified macro THROWWARNING is also provided). Warnings are definied as abnormal events which does NOT cause an immediate termination of the current (sub) function.

Returns:: Warning number returned by sub function call

Parameters:

Wnumber	Warning number returned by sub function call.
additionaltext	Additional warning text (0, if none).
functionname	Name of function which caused the warning.
filename	Name of file which caused the warning.
linenumber	Number of line which caused the warning.
localVisibilityStatus	Determines (locally) if warning message can be printed to stdFile. If GLOBAL visibility status of the message is set to VS_HIDDEN, no message is printed, anyway!
