A way to pass a file descriptor to Node? #304
Description
As compiling a NAPI module results in a library with a separate CRT, the state containing the FD table is different.
So if I have a situation where I have a HANDLE or an FD that I want to pass to Node - I find it problematic right now.
There's no API to accept a Windows' HANDLE, and no api to duplicate an FD into Node's namespace.
Anyone knows of a way to do that?
Thank you!

Basically what I'm looking for is the inverse of

Duplicate of nodejs/node#15433?

i.e. are you looking for
uv_open_osfhandleto get implemented?danielgindi commentedon Jul 18, 2018
Exactly!
uv_open_osfhandle...danielgindi commentedon Jul 18, 2018
The thing is that the whole issue is about passing an
fdacross modules, which is not possible in most cases due to separate CRTs (even if you recompile node.exe with msvcrt.dll, you must compile against the same version...)But if have a
fdyou can extract itsHANDLEand pass it on to an exporteduv_open_osfhandlefunction which will re-wrap it in its own CRT state.So right now it's possible to get an FD from node and use it in a native addon, but not vice versa.
