> We can only use what's part of the current w32api-headers package.
I occasionally contribute to mingw-w64 repository. Is there anything I can
do so that cygwin uses latest headers and libraries from mingw-w64?
To Takashi Yano:
> Then, is it possible to DuplicateHandle() for three handles in HPCON to
other process which calls ioctl() with new HPCON?
** THE FOLLOWING PROCEDURE USES UNDOCUMENTED AND UNSTABLE CODE **
To use HPCON in another process, first cast it to a pointer of struct of
three handles as below:
struct HPCON_INTERNAL {
HANDLE hWritePipe;
HANDLE hConDrvReference;
HANDLE hConHostProcess;
};
HPCON hpCon;
HRESULT hRes = CreatePseudoConsole(consoleSize, hPipePTYIn,
hPipePTYOut, 0, &hpCon);
HPCON_INTERNAL *hpConInt = hpCon;
Then **inherit** and use hpConInt->hWritePipe to write the resize signal.
Get detail information about that buffer here[1]. Sample in my repo[2].
