what do i replace all the qstring with
/apl/libapl/c > grepi qstring
./aplexec.h:18:aplExec (apl_op_e apl_op, QString &cmd,
./aplexec.h:19:QString &outString, QString &errString);
./libaplc.c:12:AplExec::aplExec (apl_op_e apl_op, QString &cmd,
./libaplc.c:13:QString &outString, QString &errString)
./libaplc.c:29:outString = QString (outbuffer.str ().c_str ());
./libaplc.c:30:errString = QString (errbuffer.str ().c_str ());
./libaplc.c:40:outString = QString (res);
./libaplc.c:44:errString = QString (errbuffer.str ().c_str ());
