Functions

func GenerateFuncType

func GenerateFuncType(fields, returns []string) *goast.FuncType

GenerateFuncType in according to types

Results: *ast.FieldList { . . Opening: - . . List: []*ast.Field (len = 1) { . . . 0: *ast.Field { . . . . Type: *ast.Ident { . . . . . NamePos: 13:21 . . . . . Name: "string" . . . . } . . . } . . } . . Closing: - . } }

func GetAllocationSizeNode

func GetAllocationSizeNode(node ast.Node) ast.Node

GetAllocationSizeNode returns the node that, if evaluated, would return the size (in bytes) of a memory allocation operation. For example:

(int *)malloc(sizeof(int))

Would return the node that represents the "sizeof(int)".

If the node does not represent an allocation operation (such as calling malloc, calloc, realloc, etc.) then nil is returned.

In the case of calloc() it will return a new BinaryExpr that multiplies both arguments.

func NewFunctionField

func NewFunctionField(p *program.Program, name, cType string) (_ *goast.Field, err error)

func TranspileAST

func TranspileAST(fileName, packageName string, p *program.Program, root ast.Node) error

TranspileAST iterates through the Clang AST and builds a Go AST
