Chr*_*ris 6 pointers go cgo
我正在使用一个 C 库,与下面不同,我无法控制它。我需要将指向也包含指针的数组的指针传递给 C 函数。
package main
/*
#include <stdio.h>
typedef int* pInt;
void foo(pInt p[]) {
printf("foo()\n");
}
*/
import "C"
import "unsafe"
func main() {
var i C.int
var p1 C.pInt = (*C.int)(unsafe.Pointer(&i))
var p2 C.pInt = (*C.int)(unsafe.Pointer(&i))
var ps []C.pInt = []C.pInt{p1, p2}
C.foo(unsafe.Pointer(&ps[0]))
}
panic: runtime error: cgo argument has Go pointer to Go pointer
