Description

dummy executable to generate valgrind suppressions.

When running code under valgrind to detect memory leaks, typically a well known set of false alarms will be reported. The reason is that some facilities, either implemented by our own or from third party libraries, just choose never to free some working buffers. To deal with this well known issue, valgrind allows to be "primed" with a specifically crafted executable, which deliberately triggers just these false memory leak alarms.

lumiera_error_set()

lumiera_err lumiera_error_set	(	lumiera_err	nerr,
		const char *	extra
	)

Set error state for the current thread.

If the error state of the current thread was cleared, then set it, else preserve the old state.

Parameters

nerr	name of the error with 'LUMIERA_ERROR_' prefix (example: LUMIERA_ERROR_NO_MEMORY)
extra	a string (possibly a constructed tmpbuf) which adds some more context to the error, can be a temporary

Returns

old state, that is NULL for success, when the state was cleared and a pointer to a pending error when the error state was already set

(

void

)

Get and clear current error state.

This function clears the error state, if it needs to be reused, one has to store it in a temporary variable.

Returns

pointer to any pending error of this thread, NULL if no error is pending
