I tried width console input and printn but it is not working.

I read it but do not understand. I have to run program A and connect to it in connect, read & write mode?
What I want is:
program A spawns my program (B)
program A sends string to stdin of B
program B reads string from stdin
after each string program B sends string to stdout
program A receive data and send new string....

ps: i wrote squid url rewriter. A is squid (own by root) and B is my program.

I wrote small test program in win and nt port of squid. Input() is reading string from stdin but I can not figure what is (or do not know how to writeprogramstringn() ) writing to stdout.

You can use ReadProgramString() and WriteProgramString() if your program launch the subprocess. Then your child program can use PrintN() and Input()

Thx 4 try but my program (B) is called by another (A).
From my testing in Windows for now... printN() is writing to stdout.
I change code a little bit and it works on Windows.
I will recompile in ubuntu 32bit later. Maybe problem is ownership (program A is own by root).

Solved! I enabled threadsafe compiler option.

What's annoying about this is that you have to open a console window first! (at least on Windows)
It would be a good idea to be able to write to stdout without the program opening a console window first.
EDIT: Okay, I spoke too soon... #PB_Program_Hide solves my problem!
