My test program will call the HW_PARAMS ioctl twice from different threads running at the same time. The first call will ask for the maximum number of periods with minimum size, the second call for the minimum number of periods of maximum size.
I cannot compile your test_hwparams.c. The local.h is missing.
You must have the alsa-lib source to compile it, that is where local.h comes from. Headers for using the alsa devices directly aren't provided from any other place.
gcc -I /path/to/alsa-lib/include -pthread test_hwparams.c
