qwf_net_GetPriorityList()

Get the interface priority list used by NET MGR

Synopsis:

#include <qwf/qwf_net.h>

qwf_net_Results_e qwf_net_GetPriorityList(qwf_Context_t *pCtx,
                                          qwf_net_IfaceList_t *const pList)

Arguments:

pCtx: A pointer to the QWF service context
pList: A pointer to a qwf_net_IfaceList_t structure for storing the priority list of network interfaces

Library:

qwf_interface

Returns:

NET_OK Successful result

NET_ERR_INACTIVE The QWF Network Manager service is inactive or not ready

NET_ERR_INT An internal error occurring while retrieving or parsing the interface data

NET_ERR_PARAM A pointer argument is NULL or the QWF Network Manager context can't be retrieved
