when I use C.dll call golang func, the programm will stuck. My golang code
is :
import (
"C"
"fmt"
"syscall"
"unsafe"
)
var times int
func main() {
cbStr := syscall.NewCallback(goCbStr)
dll, error := syscall.LoadDLL("test0001.dll")
fmt.Println(dll)
var initConnAgent *syscall.Proc
initConnAgent, error = dll.FindProc("init")
fmt.Println(initConnAgent, error)
// unsafe.
initConnAgent.Call(uintptr(unsafe.Pointer(&cbStr)))
//fmt.Println(r1, r2, lerr)
for {
}
}
func goCbStr(callId int, funtype int, str *C.char) uintptr {
times++
fmt.Println(times, callId, funtype, C.GoString(str))
return uintptr(0)
}
my c.dll code is :
void timeProc(void*P);
ADAPTERDLL_API void init(cbStr* p) {
goCallback = *p;
printf("init success!\n");
_beginthread(&timeProc, 0, 0);
printf("End \n");
}
void timeProc(void *p) {
for (;;) {
goCallback(1, 2, "Hello");
}
}
when I execute the exe, the Programm can only print about 47103 times. My
question is:
1.
How many times C.dll can call golang func ?
2.
if I can call golang func infinitely , What errors I did?
3.
