***BOGO*** Re: [Mingw-users] ANSI escape sequences problem

[Bengt Werstén <Bengt.Wersten@xxxxxxxx>]

Hi,

I have tried 2 and 3 since I'm limited to the MinGW lib in cygwin. Neither worked and it still buffers and fgetc, fread or read still return when the first enter is pressed. I used setvbuf as 
if (setvbuf(stdin, NULL, _IONBF, 0) == 0)
{
	// carry on
...

I have tried to google for more information and termios.h did show up a lot but since this is not available on MinGW there should be another way to get this to work. I tested the buffer stuff running both on bash and rxvt.

Well, it depends on what IO abstraction level you're using.  There are
at least four that come to mind off the top of my head:

1. The Win32 API level, using HANDLES, e.g. ReadFile/WriteFile.
2. The C runtime level, using file descriptors, e.g. read/write.
3. The C runtime level, using C streams (FILE *), e.g. fread/fwrite.
4. The C++ runtime level, using iostream, e.g. cin/cout.

For (3) you can disable buffering with setvbuf() with _IONBF.  For (4)
you can control buffering with foo.rdbuf()->pubsetbuf(0, 0), I think. 
(1) and (2) are AFAIK direct in that they read or write as many bytes as
specified in the call without any buffering.
