SCANGETDATA()
Prototype:
SCAN_RESULT ScanGetData(HANDLE hScanner, TCHAR * lpBuff, LPINT BufSize);
Purpose:
Returns scanned data after a successful read operation on the scanner device.
Arguments:
[in] hScanner is the value received by the client application in lParam of the WM_INSERTION message specified when ScanInit() was called.
If the application program doesn’t support callbacks, use 1 for the HANDLE (if multi-scanner disabled) .
[out] lpBuff points to the buffer to receive the scanned data.
[in/out] BufSize points to the size of the buffer in bytes (not characters). Upon return, BufSize will be set to the number of bytes written into lpBuff. This can be converted to a character count by dividing BufSize by sizeof(TCHAR). Typically the buffer size will be equal to the character count on Win32 Desktop systems.
