var FilterTokens = map[string]bool{
	"const": true,
	"enum":  true,
}

These tokens are ignored

func CamelCase(s string) string

turn some_name_blabla into SomeNameBlabla

func Render(fname string, templText string, data interface{})

Render template to file

func Tokenize(fname string) []string

Read header file, split in tokens, ignore words from filter map.

type Arg struct {
	CType, Name string
	GoType      string
}

Function argument

type Func struct {
	CName  string
	CType  string
	Args   []Arg
	GoName string
	GoType string
}

Function prototype

func ParseFuncs(tokens []string) []Func

Parse function prototypes

type TData struct {
	Funcs []Func
}

Utility type, pass to template rendering

func (*TData) CgoType(ctype string) string

Map C type to cgo type. E.g.:

int -> C.int

func (*TData) GoName(cname string) string

Turn C function name into idiomatic, exported Go name.

func (*TData) GoType(ctype string) string

Map C type to Go type, using TypeMap lookup. E.g.:

float -> float32

func (*TData) Strip(s, prefix string) string
