indicates return status. If the method returns a negative value, it failed. If
the 12-bit facility code (bits 16–27) is set to 0x007, the value contains a
Win32 error code in the lower 16 bits. Zero or positive values indicate
success, with the lower 16 bits in positive nonzero values containing warnings
or flags defined in the method implementation. For more information about Win32
