csoundGetMIDIDevList - return clients also with jack module

[tarmoj]

Enhancement:

Getting cliets list with csoundGetMIDIDevList for jack is not implemented yet. Hopefully in future!

Code for testing:

// compile gcc -DUSE_DOUBLE -o cs-test cs-test.c -lcsound64 

#include <csound/csound.h>
#include <stdio.h>

void getMidiNames(const char *module) {
    CSOUND *cs = csoundCreate(NULL);
    csoundSetMIDIModule(cs, module);
    int i,newn, n = csoundGetMIDIDevList(cs,NULL,0);
    CS_MIDIDEVICE *devs = (CS_MIDIDEVICE *) malloc(n*sizeof(CS_MIDIDEVICE));
    newn = csoundGetMIDIDevList(cs,devs,0);

    printf("Module %s %i devices found\n", module, newn);
    for (i = 0; i < n; i++) {
            printf("Device no %d: name: %s interfacename: %s\n", i, devs[i].device_name, devs[i].interface_name);
    }
    free(devs);
    csoundDestroy(cs);
}

int main(int argc, char **argv)
{
  getMidiNames("alsaseq");
  getMidiNames("jack");
  return 0;
}

Implemented now.

Thanks!

I pulled, I can see changes in rtjack.c, rebuilt but the code below code return still 0 devices for jack (alsa works as expected):

---

void getMidiNames(const char module) { CSOUND cs = csoundCreate(NULL); csoundSetMIDIModule(cs, module); int i,newn, n = csoundGetMIDIDevList(cs,NULL,0); CS_MIDIDEVICE devs = (CS_MIDIDEVICE ) malloc(n*sizeof(CS_MIDIDEVICE)); newn = csoundGetMIDIDevList(cs,devs,0);

printf("Module %s %i devices found\n", module, newn);
for (i = 0; i < n; i++) {
        printf("Device no %d: name: %s interfacename: %s\n", i,

devs[i].device_name, devs[i].interface_name); } free(devs); csoundDestroy(cs);

}

int main(int argc, char **argv) { getMidiNames("alsaseq"); getMidiNames("jack"); return 0; }

Well, it works here. Tested with

csound -+rtmidi=jack -+rtaudio=jack --midi-devices

When I first run it, I got 0 devices, but then I realised I had to turn MIDI on in jack. I got this printout then:

ligeti:debug victor$ ./csound -+rtmidi=jack -+rtaudio=jack --midi-devices

This is what happens if I run jack without asking for MIDI

Oh, right, - the Csound options!

When I added these lines to code: CSOUND *cs = csoundCreate(NULL); csoundSetOption(cs,"-odac"); csoundSetOption(cs,"-+rtaudio=jack"); csoundSetOption(cs,"-+rtmidi=jack"); csoundSetMIDIModule(cs, module);

it worked fine.
