WM_CAP_FILE_ALLOCATE

	Overview

	Group

	Quick Info

The WM_CAP_FILE_ALLOCATE message creates (preallocates) a capture file of a specified size. You can send this message explicitly or by using the capFileAlloc macro.

wParam = (WPARAM) 0;

lParam = (LPARAM) (DWORD) (dwSize);

Parameters
dwSize

Size, in bytes, to create the capture file.

Return Values
Returns TRUE if successful or FALSE otherwise.

If an error occurs and an error callback function is set using the WM_CAP_SET_CALLBACK_ERROR message, the error callback function is called.

Remarks
You can improve streaming capture performance significantly by preallocating a capture file large enough to store an entire video clip and by defragmenting the capture file before capturing the clip.
