run other programm
I have the programm, that says to STDERR(not to STDOUT!): "hello world!" and this programm is compiled and I have no sources.
When I try to open this programm in another using C:
=======================================
FILE *pp = popen("hello_to_stderr.exe", "r");
int c;
string a;
while( (c=getc(pp)!=EOF ) a +=char(c);
=======================================
the "a" string doesn't get anithing! But i see the words
"hello world!" on a screen! It simply outputs the STDERR!
How can I get the STDERR thread?
And how can I make it work on both Linux and MSWindows?
