有没有办法让在Windows文件描述符非阻塞? [英] Is there way to make file descriptor non blocking in windows?
问题描述
我想端口从Linux我的code到Windows。它是这样的:
I want to port my code from linux to windows. It is something like this:
void SetNonBlocking( int filehandle )
{
int fhFlags;
fhFlags = fcntl(filehandle,F_GETFL);
if (fhFlags < 0)
{
perror("fcntl(F_GETFL)");
exit(1);
}
fhFlags |= O_NONBLOCK;
if (fcntl(filehandle,F_SETFL,fhFlags) < 0)
{
perror("fcntl(F_SETFL)");
exit(1);
}
return;
}
现在我想在窗口一样。有任何想法吗? Actualy我的文件句柄被读取,则通过创建WINAPI管侧 CreatePipe
方法。
Now I want have same in windows. Any ideas? Actualy my filehandle is read side of pipe which is created via WinApi CreatePipe
method.
推荐答案
Windows API函数 CreateNamedPipe时
有一个选项,使处理无阻塞。 (请参阅MSDN )。另见同步和重叠I MSDN文章/ Ø。顺便说一句,你可以直接使用在Windows上编译符合POSIX标准,code MinGW的或的 Cygwin的,从而避免移植的头痛。
The Windows API function CreateNamedPipe
has an option to make the handle non-blocking. (See MSDN). Also see the MSDN article on Synchronous and Overlapped I/O. BTW, you can directly compile POSIX compliant code on Windows using MinGW or Cygwin and thus avoid the headache of porting.
