此 C 代码使用的 select_wait() 函数在哪里？
在搜索 的答案时这个问题我发现此示例代码 看起来正是我需要的，只是它调用了
select_wait()
non_blocking.h 但无法定位。
select_wait() 是专有代码吗？它是我可以获得的某些 DLL 的入口点吗？如何复制 select_wait() 所做的事情？简单地忽略 select_wait() 并立即重试 BIO_read/write 调用看起来安全吗？
更新：在测试代码时，select_wait() 似乎是必要的，因为如果输入不可用，BIO_read 将挂起。然而，RSA 的示例代码在跳出 for 循环之前最多执行一次成功的 BIO_read，因此他们的代码也无法接受来自 Chrome 的 POST，如原始问题中所述。
While searching for an answer to this question I found this sample code which looks like just what I need except it calls
select_wait()
which is defined in non_blocking.h but which is otherwise unlocatable.
Is select_wait() proprietary code? Is it an entrypoint in some DLL I can get? How do I duplicate whatever select_wait() does? Does it look safe to simply ignore select_wait() and immediately retry the BIO_read/write calls?
Update: In testing the code, the select_wait() appears necessary because BIO_read will hang if input isn't available. However, RSA's sample code does at most one successful BIO_read before breaking out of the for-loop, so their code also would fail to accept a POST from Chrome as described in the original question.

显然它是专有的 BSAFE 库/框架的一部分
Apparently it's part of the proprietary BSAFE library/framework
如果您有套接字句柄，请使用 select() WinSock API函数。
If you have a socket handle, use select() WinSock API function.
