func Exec(program string, argv []string, env []string) error

func Fork() int

func Stepback(inferior *ptrace.Tracee) error

Move the instruction pointer back one. Needed after we hit a breakpoint, otherwise we'd essentially be jumping into the middle of an instruction!

func Unbreak(inferior *ptrace.Tracee, bp Breakpoint) error

Removes the given breakpoint.

func WaitUntil(inferior *ptrace.Tracee, address uintptr) error

type Breakpoint struct {
	Address uintptr // where it was inserted
	// contains filtered or unexported fields
}

func Break(inferior *ptrace.Tracee, address uintptr) (Breakpoint, error)

Inserts a breakpoint at the given address. You'll need the return value to remove the breakpoint.

func (b Breakpoint) String() string

type Type struct {
	Type dwarf.Type
	// contains filtered or unexported fields
}

func Basetype(program string, typ Type) (Type, error)

func TypeGlobalVar(program string, address uintptr) (Type, error)

identifies the type of a global variable, as given by its address.

func TypeLocal(program string, fqn string, rel int64) (Type, error)

identifies a local (parameter or local variable), described by a (fqn, offset-off-of-fptr) pair.
