Compile with:

gcc -o testfdms -L. -lfdms testfdms.c 

run with:

LD_LIBRARY_PATH=. ./fdms-test image.dd 

You should get something like this:

**Programs** Capacity: 128, Present: 98
Program 0
offset: 0xbfd55a88
preroll: 0
metronome: on
midi_sync_out: clk
mtc_frame_rate: 25
mtc offset: 00:59:57:00:00
offset mode: bar
record protect: off
