44 * Commands for ioctlsocket(), taken from the BSD file fcntl.h.
47 * Ioctl's have the command encoded in the lower word,
48 * and the size of any in or out parameters in the upper
49 * word. The high 2 bits of the upper word are used
50 * to encode the in/out status of the parameter; for now
51 * we restrict parameters to at most 128 bytes.
