是否"sendmsg"缓冲区或味精的可用内存? [英] Does "sendmsg" free memory of the buffer or msg?

问题描述

sendmsg 的缓冲区或msg的可用内存是否可用?

Does sendmsg free memory of the buffer or msg?

请对此进行指导.

推荐答案

否， sendmsg()不会释放传入的内存.它不可能这样做，因为该内存甚至可能不是来自 malloc().您可以在调用 sendmsg()之后的任何时间)释放内存，因为系统已经制作了必要的副本.

No, sendmsg() does not free the passed-in memory. It cannot possibly do so, because that memory may not even have come from malloc(). You can free() the memory any time after calling sendmsg(), as the system will have already made the necessary copies.
