stdio

The stdio is usually buffered. When I hit a breakpoint and there's a printf before the breakpoint, the printed string may still be in the buffer and I can not see it.

I know I can flush the stdio by adding some flush code in the program. Without doing this, is there any way to tell GDB to flush the stdio of the program being debugged after GDB stops? This way is more friendly when debugging a program.

On a Cisco device, I know that enabling debugging can incur a performance hit since debugging has such a high priority on the CPU.
