Hi
i can see you code is c++
I am working with libapl with fpc (freepascal) and i can capture stdout and
stderr fine in fpc coding
but the only stdout i get from ap_exec is the 0
i have apl_exec as a function and tried with either of the following definitions
function apl_exec(p : pchar) : longint; cdecl; // gives good results displayed
but stdout captures only 0
function apl_exec(p : pchar) : ansistring; cdecl; // gives nothing to screen
with apl_exec nor any stdout
