Variables ¶

var ZeroString unsafe.Pointer

ZeroString points to a null-terminated string of length 0.

Functions ¶

func HashTableSize ¶

func HashTableSize(ptr unsafe.Pointer) int

HashTableSize returns the size of the *GHashTable.

func ListSize ¶

func ListSize(ptr unsafe.Pointer) int

ListSize returns the length of the list.

func MoveHashTable ¶

func MoveHashTable(ptr unsafe.Pointer, rm bool, f func(k, v unsafe.Pointer))

MoveHashTable calls f on every value of the given *GHashTable and frees each element in the process if rm is true.

func MoveList ¶

func MoveList(ptr unsafe.Pointer, rm bool, f func(v unsafe.Pointer))

MoveList calls f on every value of the given *GList. If rm is true, then the GList is freed.

func MoveSList ¶

func MoveSList(ptr unsafe.Pointer, rm bool, f func(v unsafe.Pointer))

MoveSList is similar to MoveList, except it's used for singly-linked lists.

func NewStructNative ¶

func NewStructNative(native unsafe.Pointer) unsafe.Pointer

NewStructNative creates a new Go struct from the given native pointer. The finalizer is NOT set.

func SListSize ¶

func SListSize(ptr unsafe.Pointer) int

SListSize returns the length of the singly-linked list.

func SetStructNative ¶

func SetStructNative(dst, native unsafe.Pointer)

SetStructNative sets the native value inside the Go struct value that the given dst pointer points to. It can be used like so:

var rec Record
SetStructNative(&rec, cvalue) // T(cvalue) = *namespace_record

func StructIntern ¶

func StructIntern(ptr unsafe.Pointer) *struct{ C unsafe.Pointer }

StructIntern returns the given struct's internal struct pointer.

func StructNative ¶

func StructNative(ptr unsafe.Pointer) unsafe.Pointer

StructNative returns the underlying C pointer of the given Go record struct pointer. It can be used like so:

rec := NewRecord(...) // T = *Record
c := (*namespace_record)(StructPtr(unsafe.Pointer(rec)))
