详细描述

Device-related methods.

The interface class gets device-related information.

成员函数说明

destroy()

virtual void nertc::IDeviceCollection::destroy ( )

pure virtual

Releases all IDeviceCollection resources.

getCount()

virtual uint16_t nertc::IDeviceCollection::getCount ( )

pure virtual

Gets the number of devices.

注解

You must call enumeratePlayoutDevices or enumerateRecordDevices before calling the method to get the number of playing and capturing devices.

返回

The number of capturing and playback devices.

getDevice()

virtual int nertc::IDeviceCollection::getDevice ( uint16_t  index, char  device_name[kNERtcMaxDeviceNameLength], char  device_id[kNERtcMaxDeviceIDLength]  )

pure virtual

Gets the device information of the specified index.

参数

index	specifies the device information that you want to check. The value must be lower than the value returned by getCount.
device_name	Device name.
device_id	Device ID.

返回

• 0: Success.
• Other values: Failure.

getDeviceInfo()

virtual int nertc::IDeviceCollection::getDeviceInfo ( uint16_t  index, NERtcDeviceInfo *  device_info  )

pure virtual

Searches specified information about index-related devices.

注解

The link method of returnable devices and the non-useful status determined by the SDK.

参数

index	specifies the device information that you want to check.
device_info	For information about device information, see NERtcDeviceInfo.

返回

• 0: Success.
• Other values: Failure.
