Function Documentation

xbps_array_foreach_cb()

int xbps_array_foreach_cb	(	struct xbps_handle *	xhp,
		xbps_array_t	array,
		xbps_dictionary_t	dict,
		int(*	fn )(struct xbps_handle *, xbps_object_t obj, const char *, void *arg, bool *done),
		void *	arg )

Executes a function callback (fn) per object in the proplib array array.

Parameters

[in]	xhp	The pointer to the xbps_handle struct.
[in]	array	The proplib array to traverse.
[in]	dict	The dictionary associated with the array.
[in]	fn	Function callback to run for any pkg dictionary.
[in]	arg	Argument to be passed to the function callback.

Returns

0 on success (all objects were processed), otherwise the value returned by the function callback.

xbps_array_foreach_cb_multi()

int xbps_array_foreach_cb_multi	(	struct xbps_handle *	xhp,
		xbps_array_t	array,
		xbps_dictionary_t	dict,
		int(*	fn )(struct xbps_handle *, xbps_object_t obj, const char *, void *arg, bool *done),
		void *	arg )

Executes a function callback (fn) per object in the proplib array array. This is a multithreaded implementation spawning a thread per core. Each thread processes a fraction of total objects in the array.

Parameters

[in]	xhp	The pointer to the xbps_handle struct.
[in]	array	The proplib array to traverse.
[in]	dict	The dictionary associated with the array.
[in]	fn	Function callback to run for any pkg dictionary.
[in]	arg	Argument to be passed to the function callback.

Returns

0 on success (all objects were processed), otherwise the value returned by the function callback.
