❔ Using STARTUPINFOEXW on PInvoke.CreateProcess - how to move from ref / out to pointer?

I'm using CsWin32 but I'm having trouble calling

PInvoke.CreateProcess

PInvoke.CreateProcess

using a

STARTUPINFOEXW

STARTUPINFOEXW

instead of a

STARTUPINFOW

STARTUPINFOW

at argument 9 (

in info

in info

).
Looking at https://github.com/microsoft/CsWin32/issues/917 it says to instead of doing

PInvoke.CreateProcess(null, ref cmdLine, null, null, false, PROCESS_CREATION_FLAGS.EXTENDED_STARTUPINFO_PRESENT, null, null, in info, out var processInformation);

PInvoke.CreateProcess(null, ref cmdLine, null, null, false, PROCESS_CREATION_FLAGS.EXTENDED_STARTUPINFO_PRESENT, null, null, in info, out var processInformation);

I should use the variant using pointers... but I can't seem to figure out how to correctly refer to my

Span<char> cmdLine = stackalloc char[execPath.Length];

Span<char> cmdLine = stackalloc char[execPath.Length];

and my

STARTUPINFOEXW info = new STARTUPINFOEXW()

STARTUPINFOEXW info = new STARTUPINFOEXW()

using pointers or replacing

out var

out var

with pointers
