[Haskell-beginners] parse C header files and transformation

Hello list, How to do some C header files parsing and automatic code transformation. like: parse this header file, and generate code for this API: int gettimeofday(struct timeval *tv, struct timezone *tz); generated code(automatically call the API, and dump the structure appropriately): void dump_time(void) { struct timeval tv = {0}; struct timezone tz = {0}; gettimeofday(&tv, &tz); printf("tv_sec: %d, tv_usec: %d\n", tv.tv_sec, tv.tv_usec); printf("tz_minuteswest: %d, tz_dsttime: %d\n", tz.tz_minuteswest, tz.tz_dsttime); } because I'm working on a SDK which has hundreds of API to set and get headware states. It'll will be very nice to write some haskell code to parse the header files and generate C code that can dump hardware state automatically. BR Ted
