//! \brief SOCKET APIs Implements file.
|
|
//! \details SOCKET APIs like as Berkeley Socket APIs.
|
|
//! \version 1.0.3
|
|
//! \date 2013/10/21
|
|
//! \par Revision history
|
|
//! <2015/02/05> Notice
|
|
//! The version history is not updated after this point.
|
|
//! Download the latest version directly from GitHub. Please visit the our GitHub repository for ioLibrary.
|
|
//! >> https://github.com/Wiznet/ioLibrary_Driver
|
|
//! <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
