Second, we need functions, data structures, and macros to create and update
lists of attributes for process and thread creation.
Okay. In the absence of any third party patch submissions, I decided to have a
look into this, myself.
These are:
* InitializeProcThreadAttributeList function
* UpdateProcThreadAttribute function
* DeleteProcThreadAttributeList function
I can find prototypes for these, on docs.microsoft.com, so no problem to add
them to <winbase.h>. AFAICT, they should be available from Vista onwards — in
fact, they must be if STARTUPINFOEX is, because the additional data which this
incorporates, over STARTUPINFO itself, cannot be manipulated without them.
* PROC_THREAD_ATTRIBUTE_LIST structure
AFAICT, this is undocumented (by Microsoft), but maybe we can get away with a
opaque declaration, since this should only ever be accessed via an
LPPROC_THREAD_ATTRIBUTE_LIST pointer, and manipulated using the preceding three
functions.
* STARTUPINFOEX structure
Once again, I can implement this, in terms of the documentation on
docs.microsoft.com.
* PROC_THREAD_ATTRIBUTE_PSEUDOCONSOLE macro
* Other PROC_THREAD_ATTRIBUTE_* macros
What do you mean by other PROC_THREAD_ATTRIBUTE_* macros? I'm guessing you are
referring to those enumerated as valid for the Attribute parameter of
UpdateThreadAttribute(), but that documentation is utterly useless, because the
enumeration is no more than a meaningless list of macro names; it does not
specify appropriate values for any of those macros.
These seem to be supported since Windows 7, with the exception of
PROC_THREAD_ATTRIBUTE_PSEUDOCONSOLE, which is only supported since Windows 10,
and STARTUPINFOEX, which is supported since Vista. I think the proper place
for them is in the winbase.h header file.
Actually, some seem to be supported in Vista, some in Win7, and some not until
Win8; PROC_THREAD_ATTRIBUTE_PSEUDOCONSOLE appears not to be supported even for
all Win10, but only from Win10-v1809 (October 2018 update). I agree that
<winbase.h> is the appropriate header for deployment, but that hardly matters;
the lack of appropriate publicly accessible documentation is a blocker! Unless
someone can provide appropriate third-party documentation, (not copies of
Microsoft SDK headers), this request cannot be fulfilled.
We also need the EXTENDED_STARTUPINFO_PRESENT flag for the CreateProcess
function (this flag is supported since Vista and should be in winbase.h).
This one is easy enough; it is adequately documented here.

Ticket details:
To compile programs that use the Pseudo Console feature introduced recently
with Windows 10, there's a need in several additions to the MinGW w32api
headers and import libraries.
First, we need a value for _WIN32_WINNT that specifies Windows 10, in
sdkddkver.h:
#define _WIN32_WINNT_WIN10 0x0A00
Second, we need functions, data structures, and macros to create and update
lists of attributes for process and thread creation. These are:
InitializeProcThreadAttributeList function
UpdateProcThreadAttribute function
DeleteProcThreadAttributeList function
PROC_THREAD_ATTRIBUTE_LIST structure
STARTUPINFOEX structure
PROC_THREAD_ATTRIBUTE_PSEUDOCONSOLE macro
Other PROC_THREAD_ATTRIBUTE_* macros
These seem to be supported since Windows 7, with the exception of
PROC_THREAD_ATTRIBUTE_PSEUDOCONSOLE, which is only supported since Windows 10,
and STARTUPINFOEX, which is supported since Vista. I think the proper place
for them is in the winbase.h header file.
We also need the EXTENDED_STARTUPINFO_PRESENT flag for the CreateProcess
function (this flag is supported since Vista and should be in winbase.h).
And finally, we need the functions, data types, and macros to manipulate
pseudo-consoles, available only since Windows 10:
CreatePseudoConsole function
ClosePseudoConsole function
ResizePseudoConsole function
HPCON data type
Thanks in advance for providing these.
