This function closes a ScanHandle and releases the associated Scan Result Block to the pool. This function MUST be called once for each ScanHandle produced in a scan...() function. Once this function is called the ScanHandle is no longer valid and any pointers returned by previous calls to get...() functions should be discarded (forgotten, not freed!)

ScanHandle = a valid scan handle from scanBuffer() or scanFile().

returns:

snf_SUCCESS - The ScanHandle was closed successfully.

snf_ERROR_NO_HANDLE - The ScanHandle is not valid.

snf_ERROR_EXCEPTION - There was a problem closing the ScanHandle.
