That is C. It looks like it is written to be called from a Python program.

Clues that it is C rather than python:
  # compiler directives (e.g. #include)
  Variable declarations e.g. static ..., extern ...
  Use of {} to group statements
  Use of ; to terminate statements
  Use of /* */ to enclose comments
