Function Documentation

void error_detected	(	uint32_t	errnum,
		const char *	errstr,
			...
	)

Call this when an error is first detected.

It sets the error code and it also sets the primary error string, describing the lowest level of error. (Actually, it appends to the error string.)

If the error code is already set, then this appends to the primary error string an hex representation of the new error code, plus the new error message.

Parameters

errnum	The desired error code
errstr	The format string for the error message

void error_returned	(	const char *	errstr,
			...
	)

Call this when a called TSK function returns an error.

Presumably, that function will have set the error code and the primary error string. This appends to the secondary error string. It should be called to describe the context of the call. If no error code has been set, then this sets a default code so that it is not zero.

Parameters

errstr

The format string for the error message
