IltmmCapture::CopyTarget

#include "ltmm.h"

C Syntax	HRESULT IltmmCapture_CopyTarget(pCapture, FileName, AllowEscAbort)
C++ Syntax	HRESULT CopyTarget(FileName, AllowEscAbort)

IltmmCapture *pCapture;	/* pointer to an interface */
BSTR FileName;	/* name of the file */
VARIANT_BOOL AllowEscAbort;	/* flag */

Copies the valid media data from the target to the specified file.

Parameter	Description
pCapture	Pointer to an IltmmCapture interface.
FileName	Character string containing the destination file name. Valid data is copied to this file.
AllowEscAbort	Flag that determines whether pressing the ESC key will abort the copy operation. Possible values are:
	Value	Meaning
	VARIANT_TRUE	Pressing the ESC key will abort the copy operation.
	VARIANT_FALSE	Pressing the ESC key will not abort the copy operation.

Returns

S_OK	The function was successful.
<> S_OK	An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation.

Comments

The new file will contain only valid data and therefore can be much shorter than the target. Typically, you will always capture to the same huge pre-allocated target and use this method to copy the data you want to save from each capture to a new file.
