GtDio6xFileSetVectorStartCount

File

Sets the number of vectors and the starting offset in the file.

GtDio6xFileSetVectorStartCount (hFile, dwVectorStart, dwVectorCount, pnStatus)

Name	Type	Comments
hFile	SHORT	Session identifier: ● File handle is used when communicating with a file. The File handle session identifier is returned by calling GtDio6xFileOpen.
dwVectorStart	DWORD	Sets the vector start offset.
dwVectorCount	DWORD	Sets the number of the vectors.
pnStatus	PSHORT	Returned status: 0 on success, negative value on failure.

This function set the number of vectors and the starting offset in the file.

The following example opens an existing file, sets the channel count to 32, sets the number of vectors to 1024, and close the file.

SHORT nStatus;

GtDio6xFileOpen(“C:\\MyFile.dio6x”, GTDIO6X_FILE_READ_WRITE, &hFile, &nStatus);

GtDio6xFileSetChannelCount(hFile, 32, &nStatus);

GtDio6xFileSetVectorStartCount(hFile, 0, 1024, &nStatus);

GtDio6xFileClose(hFile, &nStatus);
