Function tst_timeout() added into LTP test interface:
tst_timeout "command arg1 arg2 ..." timeout
Function enables waiting for specified command for timeout
seconds. Example usage:
cmd_output=$(tst_timeout "ping -c 3 localhost" 5)
if [ $? -ne 0 ]; then
tst_brkm TBROK "timeout reached!"
fi
where $cmd_output contains stdout and stderr of ping command.
