Fanuc Focas Python

# Get current program number
prog_num = ctypes.c_ulong()
ret = focas.cnc_rdprgnum(handle, ctypes.byref(prog_num))
if ret == 0:
print(f"Current Program: Oprog_num.value")

FOCAS functions often require C structures (structs) to pass data back and forth. We must replicate these in Python. fanuc focas python
