c++ - Cant pass pipe's write-end as file desctiptor

Question

Pipe's write-end file descriptor is int but some functions such Tcl_MakeFileChannel accepts void* as file handle. I need to pass pipe write-end to it. How can one convert one type of file handle to another?

阅读此参考资料，您似乎只需传递文件描述符：

Tcl_MakeFileChannel(reinterpret_cast<void*>(fd), ...);
