<font face="Arial">Hi Gary,<br>
<br>
I did this:<br>
<br>
//------------------------------------------------<br>
<br>
RtAudio::StreamOptions options;<br>
options.flags = RTAUDIO_MINIMIZE_LATENCY;<br>
options.flags = RTAUDIO_SCHEDULE_REALTIME;<br>
options.flags = RTAUDIO_HOG_DEVICE;<br>
options.flags = RTAUDIO_ALSA_USE_DEFAULT;<br>
options.numberOfBuffers = 2;<br>
options.priority = max;<br>
<br>
<br>
std::cout << "\nPriority min: " << min <<
std::endl;<br>
std::cout << "\nPriority max: " << max <<
std::endl;<br>
<br>
// min and max are 1 and 99 ...<br>
<br>
struct sched_param sched_p;<br>
//std::cout << "\nPriority IST: " <<
sched_getparam(getpid(), &sched_p) << std::endl;<br>
std::cout << "\nPriority IST: " << sched_getparam(0,
&sched_p) << std::endl;<br>
<br>
</font><font face="Arial">//------------------------------------------------<br>
<br>
For the last line I get always "0". I is in an Linux environment
with RT-Kernel (only command-line OS). The same with another
"normal" Kernel and XFCE... The task manager also shows "0".<br>
<br>
Do you have any idea?<br>
<br>

<pre wrap="">Hi Tomas,
The "priority" option is only used if you also set the RTAUDIO_SCHEDULE_REALTIME flag. The priority value (a number) corresponds to the linux realtime scheduling system … I can't remember the valid range of values, though whatever you provide is checked against:
int min = sched_get_priority_min( SCHED_RR );
int max = sched_get_priority_max( SCHED_RR );

<pre wrap="">Hi everybody,
I am changing some things to bring my Windows application to Linux. I want to use the StreamOption "priority".
Am I right to to use it this way (the second line)? May be also a second process - the process name of my application?
RtAudio::StreamOptions options;
options.priority = ALSA;
My other question: In Windows I used system keyboard events like this to control the command-line app from outside:
(Ctrl+o)
if(GetAsyncKeyState(VK_CONTROL)&&GetAsyncKeyState(0x4F))
{
...
}
For Linux I couln't find something similar. What would be a "light-weight" solution: Using SDL (only keyboard-events)?
Thanks a lot!
Regards
Thomas
