EVM6678le CCS5.3 导入例程D:\ti\BIOS_MCSDK_02_01_02_06_p1\mcsdk_2_01_02_06\examples\ndk\helloWorld\evmc6678l
原程序已经调通..但我不想用TI 本身的SERVER SUITE
想自己直接写SOCKET
修改代码如下.
int connect_nonb(SOCKET s, PSA sin, int msecs)
{
int nonb;
fd_set fdset;
struct timeval tv;
nonb = 0;
if ( setsockopt( s, SOL_SOCKET, SO_BLOCKING, (void*)&nonb, sizeof( int ) ) != 0 )
{
return -1;
}
if ( connect( s, ( PSA ) sin, sizeof( struct sockaddr ) ) != 0 )
{
FD_ZERO( &fdset );
FD_SET( s, &fdset );
tv.tv_sec = msecs / 1000;
tv.tv_usec = (msecs % 1000) * 1000;
if ( fdSelect( 0, 0, &fdset, 0, &tv ) != 1 )
{
return -1;
}
}
nonb = 1;
if ( setsockopt( s, SOL_SOCKET, SO_BLOCKING, (void*)&nonb, sizeof( int ) ) != 0 )
{
return -1;
}
return 0;
}

其它没动...每次执行到connect 程序就动不了.....非阻塞也没用
