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.

There are two different ways to call between Go and C/C++ code.

The first is the cgo tool, which is part of the Go distribution. For
information on how to use it see the cgo documentation (go doc cmd/cgo).
