Type Mapping between C and Go

C type	Go Type	Note
char	c.Char	int8
short	int16
int	c.Int
long	c.Long
long long	int64	c.LongLong
unsigned char	byte	uint8
unsigned short	uint16
unsigned int	c.Uint
unsigned long	c.Ulong
unsigned long long	uint64	c.UlongLong
size_t	uintptr
ssize_t	int	sizeof(int) = sizeof(uint) = sizeof(uintptr) in Go
float	float32	c.Float
double	float64	c.Double
complex float	complex64
complex double	complex128
void*	c.Pointer
T*	*T
T[] (in parameter)	*T
T[N] (in parameter)	*T	fake array
T[N] (in struct)	[N]T	array
func ptr (in parameter)	func	LLGo knows `func ptr` in C function parameters is `func ptr` not `closure`
func ptr (in struct)	c.Pointer	C `func ptr` not Go `func()`
struct	struct
