Allow console allocation policies that are finer-grained than the PE image subsystem #7335
Description
Due to the design of the console subsystem on Windows as it has existed
since Windows 95, every application that is stamped with the
IMAGE_SUBSYSTEM_WINDOWS_CUI subsystem in its PE header will be
allocated a console by kernel32 (conclnt, the console client library,
handles this.)
Any application that is stamped IMAGE_SUBSYSTEM_WINDOWS_GUI will not
automatically be allocated a console.
We need something finer-grained than that.
This scenario workitem includes:
- Creating the new fusion manifest entry
- Adding support for the fusion manifest entry to conclnt
- Any APIs that must be added (e.g.
AllocConsoleEx) to support this new policy - All testing for any new APIs and fusion manifest fields
- All public facing documentation for any new APIs and fusion manifest fields
