+//! \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
