[英]Convert a HANDLE to File Descriptor
I have a HANDLE like that: 我有一个类似的句柄:
HANDLE hPipe = CreateNamedPipe(...)
Is possible to convert the hPipe to a File Descriptor (int)? 可以将hPipe转换为文件描述 (INT)?
I need this because I have implemented in C++ a code to work with TLS using the OpenSSL. 我需要这样做,因为我已经在C ++中实现了使用OpenSSL使用TLS的代码。 This is working like a charm with TCP sockets, but I really need use it over Namedpipe. 这与TCP套接字的工作原理一样,但是我确实需要在Namedpipe上使用它。
The OpenSSL's function SSL_set_fd(SSL *ssl, int fd) accepts just FileDescriptor that is a int , and not a HANDLE . OpenSSL的函数SSL_set_fd(SSL * ssl,int fd)仅接受作为int的 FileDescriptor ,而不接受HANDLE 。
Note: I also tried use the below function, but doesn't worked (return 3): 注意:我也尝试使用以下功能,但不起作用(返回3):
int fd = _open_osfhandle(reinterpret_cast<intptr_t>(hPipe), 0);
The 3
you're getting back isn't an error, it's the file descriptor handle. 您要返回的3
不是错误,它是文件描述符句柄。 If you look at the documentation you'll see that it returns -1
for failure, otherwise the return value is a file descriptor. 如果查看文档,您会发现它为失败返回-1
,否则返回值为文件描述符。
