Re: [Dev-C++] WinMain()

[Per W. <pw...@ia...>]

I haven't done a lot of work with Developer Studio .NET, so I can't say
about your problem with a console + GUI but anyway...

The original main() only takes 8-bit characters as parameters, making it
unsuitable for unicode programs.

To better support unicode, you now get a
int _tmain(int argc, _TCHAR* argv[]);

where _tmain will conditionally compile to
  int main(int argc,char* argv[]);
or
  int wmain(int argc,wchar_t* argv[]);
depending on if you compile your program with _UNICODE defined.

I can't say what difference it is between tmain() and _tmain(). I only
have a DevStudio 6.0 in front of me right now, and it only have the _tmain
declaration.

Normally, it is a question of linker flags if the program expects to find
a main() or a WinMain(), where main() is expected for console
apptiocations and WinMain() for GUI applications.

I have had a couple of DevStudio 6 projects goof up quite a lot when
letting DevStudio upgrade them to DevStudio.NET. A number of compiler and
linker settings have become quite interesting :-)

 The

not find it strange. The strange thing is that for GUI the only option
available is Win32 project. Anyway i "stole" its WinMain and placed it in

Win32? (just from curiosity).=0D

[<cg...@wo...>]

Sorry, no experience with NET, but I can answer to one or mmore questions:

> What __stdcall is supposed to

It says that the procedure called is responsible of removing the 
parameters from the stack, cdecl, which is the standard in C, says it is 
the caller which does that. __stdcall is the form of the WINAPI C 
functions, in fact it is synonimoius of far __pascal, and synonimous of 
WINAPI. So it is valid.

I don't know that, I only know they're not in my WINAPI reference.

[Dev-C++] assembly with gas

[<cg...@wo...>]

  Someone knows about some site with good enough tutorials for 
programming in gas assembly? (AT&T syntax). I only found: Linux 
assembly: gas uses AT&T syntax instead the usual Intel from NASM, so 
let's learn NASM. And no word about gas. The only two sites I found with 
some info about it are not enough
