// CONASearchDevices
//
// Description:
// CCONASearchDevices functions search all devices from the target media.
// The target media that can be used is Bluetooth at the moment.
//
// CONASearchDevices allocates and sets devices information to
// CONAPI_CONNECTION_INFO structs and returns pointer to structs.
// Connectivity API-user MUST releases the returned pointer by calling the
// CONAFreeConnectionInfoStructures function.
//
// Every CONAPI_CONNECTION_INFO struct includes the media and device information.
// The struct's dwState parameter defines the paired and trusted information from
// device. It has the following values:
// Parameter value Description Macros for check the values
// (If value is true, macro returns 1)
// CONAPI_DEVICE_UNPAIRED Device in not paired. CONAPI_IS_DEVICE_UNPAIRED(dwState)
// CONAPI_DEVICE_PAIRED Device is paired. CONAPI_IS_DEVICE_PAIRED(dwState)
// CONAPI_DEVICE_PCSUITE_TRUSTED Device is PC Suite trusted. CONAPI_IS_PCSUITE_TRUSTED(dwState)
//
// Connectivity API can add more values afterwards so Connectivity API-user should
// always use defined macros to check those values!
//
// Parameters:
// hDMHandle [in] Existing device management handle.
// dwSearchOptions [in] Search options values:
// API_MEDIA_BLUETOOTH: Get devices from bluetooth media.
// This value must be used.
// CONAPI_ALLOW_TO_USE_CACHE: Get all devices from cache if available.
// If cache is not available function fails with error: ECONA_CACHE_IS_NOT_AVAILABLE.
// This value is optional and can be used with other values.
// One of the next values can be used at the time:
// CONAPI_GET_ALL_PHONES: Get all phones from target media. Includes unpaired,
// paired and PC Suite trusted phones.
// CONAPI_GET_PAIRED_PHONES:Get all paired phones from target media. Includes
// paired (and PC Suite trusted) phones.
// CONAPI_GET_TRUSTED_PHONES:Get all PC Suite trusted phones from target media.
// Includes all PC Suite trusted phones, which are paired.
// dwSearchTime [in] Maximum search time in seconds. Note: Bluetooth device
// discovery can takes several minutes if there are a lot of devices on range!
// pfnSearchNotify [in] Pointer to search notification callback function. Value
// can be NULL if notification is not needed.
// pdwNumberOfStructures [out] Number of CONAPI_CONNECTION_INFO structures.
// ppConnInfoStructures [out] Pointer to CONAPI_CONNECTION_INFO structure(s).
// hDMHandle [in] Device manager handle
// pstrSerialNumber [in] Serial number of the device.
// pstrNewFriendlyName [in] New Device Friendly Name .
//
// Return values:
// CONA_OK
// ECONA_INVALID_POINTER
// ECONA_INVALID_HANDLE
// ECONA_DEVICE_NOT_FOUND
// ECONA_FAILED_TIMEOUT
// ECONA_NO_CONNECTION_VIA_MEDIA
// ECONA_MEDIA_IS_NOT_WORKING
// ECONA_CACHE_IS_NOT_AVAILABLE
// ECONA_SUSPEND
// ECONA_NOT_ENOUGH_MEMORY
// ECONA_NOT_INITIALIZED
// ECONA_NOT_SUPPORTED_PC
// ECONA_CANCELLED
// ECONA_UNKNOWN_ERROR
