You can send the data(20K) directly and no need to concern the data order that TCP had done itThe only thing you must concern is to deal the recv data on the recv endpoint
The data was copied to kernel buffer sequence when you call send functionThe default max stack size is about 1M in apand What`s the size in masm?you should check it
另外,tcp是保证次序的
2 如果是阻塞方式的,你按12345的顺序send,那么recv的时候,也是严格按照12345接收的,不会出现顺序错误
