[BRLTTY] keycode brlapi no names

[Quartel, Eric de]

Hello there,
I run brltty on a raspberrypi raspbian version Buster.
This has mawk version:
mawk 1.3.3 Nov 1996, Copyright (C) Michael D. Brennan
An old version but it does not come with a newer one.

When i have the apiclient running with the following code:
/* get the keycodes*/
size_t len;
brlapi_param_keyCode_t *keys=brlapi_getParameterAlloc(BRLAPI_PARAM_DEVICE_KEY_CODES,0,1,&len);
len/=sizeof(*keys);
for (int j=0; j<len;j++){
  char *name=brlapi_getParameterAlloc(BRLAPI_PARAM_KEY_SHORT_NAME,keys[j],1,NULL);
  fprintf(stderr, "Key: %x Name: %s\n",keys[j],name);
  free(name);
  }
free(keys);
I get this output with no names, have also tried a freedom scientific, all with same results:
