socket non blocking
近日學習用C++實作Socket Server與Client 端的程式，線上有許多Code都蠻完整的，但多數並非Non Blocking Socke., What do you mean by "not always reliable"? If the system succeeds in setting your socket non non-blocking, it will be non-blocking. Socket operations will return EWOULDBLOCK if they would block need to block (e.g. if the output buffer is full a

將socket 設定為non-blocking（非阻塞），你就能"poll（輪詢）" socket 以取得資訊。如果你試著讀取non-blocking socket，而socket 沒有資料時，函式就不會發生block，而是傳回-1，並將errno 設定為EWOULDBLOCK。 然而，一般來說，這樣polling 是不好的想法。如果你讓程式一直忙著查socket 上是否有資料... http://beej-zhtw.netdpi.net [C++]Non Blocking Socket (Server端) | 軟工Egan的學習筆記- 點部落

而那幾個名詞就是在這兩個步驟上有些許差異，blocking I/O是Linux socket programming的default行為. blocking I/O就是當你call了recvfrom之後，一定要等，等到收完才叫結束，然後recefrom的return value就是收進來多少，若是一直沒資料進來，你的process就會被卡死在那。 在講non-blocking之前，我們先講I/O ... https://wirelessr.gitbooks.io |
