Functions

func FindMacros

func FindMacros(env *BuildEnv, r io.Reader) ([]string, error)

FindMacros returns the names of all macros defined by the C source in r.

func Preprocess

func Preprocess(env *BuildEnv, r io.Reader) ([]byte, error)

Preprocess invokes the C preprocessor to pre-process the C source in r.

Types
