//! \file socket.c
//! \brief SOCKET APIs Implements file.
//! \details SOCKET APIs like as Berkeley Socket APIs.
//! \version 1.0.3
//! \date 2013/10/21
//! \par Revision history
//! <2014/05/01> V1.0.3. Refer to M20140501
//! 1. Implicit type casting -> Explicit type casting.
//! 2. replace 0x01 with PACK_REMAINED in recvfrom()
//! 3. Validation a destination ip in connect() & sendto():
//! It occurs a fatal error on converting unint32 address if uint8* addr parameter is not aligned by 4byte address.
//! Copy 4 byte addr value into temporary uint32 variable and then compares it.
//! <2013/12/20> V1.0.2 Refer to M20131220
//! Remove Warning.
//! <2013/11/04> V1.0.1 2nd Release. Refer to "20131104".
//! In sendto(), Add to clear timeout interrupt status (Sn_IR_TIMEOUT)
//! <2013/10/21> 1st Release
