copy command

The copy command copies data to the clipboard. Digital-video devices recognize this command.

To send this command, call the mciSendString function with the lpszCommand parameter set as follows.

_stprintf_s(
  lpszCommand, 
  TEXT("copy %s %s %s"), 
  lpszDeviceID, 
  lpszItem, 
  lpszFlags
); 

Parameters

lpszDeviceID

Identifier of an MCI device. This identifier or alias is assigned when the device is opened.

lpszItem

One of the following flags identifying the item to copy.

Value	Meaning
at rectangle	Specifies the portion of each frame that will be copied. If omitted, the default setting is the entire frame.
audio stream stream	Specifies the audio stream in the workspace affected by the command. If you use this flag and also want to copy video, you must also use the "video stream" flag. (If neither flag is specified, all audio and video streams are copied.)
from position	Specifies the start of the range copied. If omitted, the default setting is the current position.
to position	Specifies the end of the range copied. The audio and video data copied are exclusive of this position. If omitted, the default setting is the end of the workspace.
video stream stream	Specifies the video stream in the workspace affected by the command. If you use this flag and also want to copy audio, you must also use the "audio stream" flag. (If neither flag is specified, all audio and video streams are copied.)

lpszFlags

Can be "wait", "notify", "test", or a combination of these. For more information about these flags, see The Wait, Notify, and Test Flags.

Return Value

Returns zero if successful or an error otherwise.
