The standard C numeric types are available under the names
C.char, C.schar (signed char), C.uchar (unsigned char),
C.short, C.ushort (unsigned short), C.int, C.uint (unsigned int),
C.long, C.ulong (unsigned long), C.longlong (long long),
C.ulonglong (unsigned long long), C.float, C.double,
C.complexfloat (complex float), and C.complexdouble (complex double).
The C type void* is represented by Go's unsafe.Pointer.
