You currently can not. Most platforms have the envp() pointer available, but
this is of course not very user friendly. I have added the
Function EnvironmentVariableCount() : Integer;
Function GetEnvironmentString(Index : Integer) : String;
functions to sysutils. (still needs committing, should be there shortly)
Thanks. No need to hurry though. I won't be using them before 1.9.6. ;-)

No, but I prefer to have them ASAP, they can be tested much longer in that
case, on all platforms.

I made a small typo, it's

Function GetEnvironmentVariableCount() : Integer;

The following should compile and run:

program testep;

uses sysutils;

Var
  I : Integer;

begin
  For I:=1 to GetEnvironmentVariableCount do
Writeln(i:3,' : ',GetEnvironmentString(i));
end.

[fpc-devel] Video.CursorX/Y 1-based under UNIX

[Michalis Kamburelis]

Hi.
I'm just playing with unit Video and I found some strange thing. It 
looks like a bug in my opinion, but it's so obviously implemented in 
Video unit that I fear that it's some feature :

Under UNIXes CursorX / CursorY are 1-based. While SetCursorPos takes 
0-based parameters on all OSes, and CursorX / CursorY are 0-based on Win32.

Although docs never explicitly say that CursorX and CursorY should be 
0-based, I think that they should be, because
- SetCursorPos takes 0-based params, so obviously CursorX and CursorY 
should follow the same convention,
- under Win32 CursorX and CursorY are 0-based, and rtl/win32/video.pp is 
clearly implemented to keep this assumption.

What's strange is that looking at sources rtl/unix/video.pp, it looks 
like someone intended that behavior, i.e. that CursorX and CursorY are 
1-based.
