Return value of program being debugged

[Grzegorz Cieslewski]

Hi,

I have encountered an interesting problem.
Upon executing the program:
int main()
{
        return(-1);
}

in gdb I get the following output

(gdb) r
Starting program: /tmp/test

Program exited with code 0377.
(gdb) q

Could someone tell me how is "-1" mapped to "0377"?

Greg
