A helper to iterate over unsafe pointers.
go get -u github.com/danielgatis/go-ptrloopAnd then import the package in your code:
import "github.com/danielgatis/go-ptrloop/ptrloop"An example described below is one of the use cases.
package main /* #include <stdlib.h> #include <strings.h> char** createArray(int n) { char** array = (char **) malloc(n * sizeof(char *)); for (int i = 0; i < n; ++i) { array[i] = strdup("hello!"); } return array; } */ import "C" import ( "fmt" "unsafe" "github.com/danielgatis/go-ptrloop/ptrloop" ) func main() { n := 3 array := C.createArray(C.int(n)) ptrloop.Loop(unsafe.Pointer(array), int(n), func(ptr unsafe.Pointer, i int) bool { s := *(**C.char)(ptr) fmt.Printf("%v -> %v\n", i, C.GoString(s)) return true }) }❯ go run main.go 0 -> hello! 1 -> hello! 2 -> hello!
