Most functions are tied to a handle that is * first obtained by calling WlanOpenHandle. Usually it is followed by a call * to WlanEnumInterfaces and then for each interface a WlanScan call is made. * WlanScan starts a parallel access point discovery that delivers the ready * response through the callback registered by WlanRegisterNotification. After * that the program calls WlanGetAvailableNetworkList or WlanGetNetworkBssList. */ #include "config.h" #include <stdarg.h> #include "windef.h" #include "winbase.h" #include "wine/debug.h" #include "wlanapi.h" WINE_DEFAULT_DEBUG_CHANNEL(wlanapi); #define WLAN_MAGIC 0x574c414e /* WLAN */ static struct wine_wlan { DWORD magic, cli_version; } handle_table[16]; static struct wine_wlan* handle_index(HANDLE handle) { ULONG_PTR i = (ULONG_PTR)handle - 1; if (i < ARRAY_SIZE(handle_table) && handle_table[i].magic == WLAN_MAGIC) return &handle_table[i]; return NULL; } static HANDLE handle_new(struct wine_wlan **entry) { ULONG_PTR i; for (i = 0; i < ARRAY_SIZE(handle_table); i++) { if (handle_table[i].magic == 0) { *entry = &handle_table[i]; return (HANDLE)(i + 1); } } return NULL; } DWORD WINAPI WlanEnumInterfaces(HANDLE handle, void *reserved, WLAN_INTERFACE_INFO_LIST **interface_list) { struct wine_wlan *wlan; WLAN_INTERFACE_INFO_LIST *ret_list; FIXME("(%p, %p, %p) semi-stub\n", handle, reserved, interface_list); if (!handle || reserved || !interface_list) return ERROR_INVALID_PARAMETER; wlan = handle_index(handle); if (!wlan) return ERROR_INVALID_HANDLE; ret_list = WlanAllocateMemory(sizeof(WLAN_INTERFACE_INFO_LIST)); if (!ret_list) return ERROR_NOT_ENOUGH_MEMORY; memset(&ret_list->InterfaceInfo[0], 0, sizeof(WLAN_INTERFACE_INFO)); ret_list->dwNumberOfItems = 0; ret_list->dwIndex = 0; /* unused in this function */ *interface_list = ret_list; return ERROR_SUCCESS; } DWORD WINAPI WlanCloseHandle(HANDLE handle, void *reserved) { struct wine_wlan *wlan; TRACE("(%p, %p)\n", handle, reserved); if (!handle || reserved) return ERROR_INVALID_PARAMETER; wlan = handle_index(handle); if (!wlan) return ERROR_INVALID_HANDLE; wlan->magic = 0; return ERROR_SUCCESS; } DWORD WINAPI WlanOpenHandle(DWORD client_version, void *reserved, DWORD *negotiated_version, HANDLE *handle) { struct wine_wlan *wlan; HANDLE ret_handle; TRACE("(%u, %p, %p, %p)\n", client_version, reserved, negotiated_version, handle); if (reserved || !negotiated_version || !handle) return ERROR_INVALID_PARAMETER; if (client_version != 1 && client_version != 2) return ERROR_NOT_SUPPORTED; ret_handle = handle_new(&wlan); if (!ret_handle) return ERROR_REMOTE_SESSION_LIMIT_EXCEEDED; wlan->magic = WLAN_MAGIC; wlan->cli_version = *negotiated_version = client_version; *handle = ret_handle; return ERROR_SUCCESS; } DWORD WINAPI WlanScan(HANDLE handle, const GUID *guid, const DOT11_SSID *ssid, const WLAN_RAW_DATA *raw, void *reserved) { FIXME("(%p, %s, %p, %p, %p) stub\n", handle, wine_dbgstr_guid(guid), ssid, raw, reserved); return ERROR_CALL_NOT_IMPLEMENTED; } DWORD WINAPI WlanRegisterNotification(HANDLE handle, DWORD notify_source, BOOL ignore_dup, WLAN_NOTIFICATION_CALLBACK callback, void *context, void *reserved, DWORD *notify_prev) { FIXME("(%p, %d, %d, %p, %p, %p, %p) stub\n", handle, notify_source, ignore_dup, callback, context, reserved, notify_prev); return ERROR_CALL_NOT_IMPLEMENTED; } DWORD WINAPI WlanGetAvailableNetworkList(HANDLE handle, const GUID *guid, DWORD flags, void *reserved, WLAN_AVAILABLE_NETWORK_LIST **network_list) { FIXME("(%p, %s, 0x%x, %p, %p) stub\n", handle, wine_dbgstr_guid(guid), flags, reserved, network_list); return ERROR_CALL_NOT_IMPLEMENTED; } void WINAPI WlanFreeMemory(void *ptr) { TRACE("(%p)\n", ptr); HeapFree(GetProcessHeap(), 0, ptr); } void *WINAPI WlanAllocateMemory(DWORD size) { void *ret; TRACE("(%d)\n", size); if (!size) { SetLastError(ERROR_INVALID_PARAMETER); return NULL; } ret = HeapAlloc(GetProcessHeap(), 0, size); if (!ret) SetLastError(ERROR_NOT_ENOUGH_MEMORY); return ret; } BOOL WINAPI DllMain(HINSTANCE hinstDLL, DWORD reason, void *reserved) { TRACE("(0x%p, %u, %p)\n", hinstDLL, reason, reserved); switch (reason) { case DLL_WINE_PREATTACH: return FALSE; /* prefer native version */ case DLL_PROCESS_ATTACH: DisableThreadLibraryCalls(hinstDLL); break; } return TRUE; }
