您可以使用 setjmp 和 longjump，就像 Lua 库在内部所做的那样.这将使您摆脱 pcalls 和其他东西，而无需不断出错，防止脚本尝试处理您的虚假错误并仍然使您无法执行.(不过我不知道这对线程的作用如何.)

You could use setjmp and longjump, just like the Lua library does internally. That will get you out of pcalls and stuff just fine without need to continuously error, preventing the script from attempting to handle your bogus errors and still getting you out of execution. (I have no idea how well this plays with threads though.)

#include <stdio.h>
#include <setjmp.h>
#include "lua.h"
#include "lualib.h"
#include "lauxlib.h"

jmp_buf place;

void hook(lua_State* L, lua_Debug *ar)
{
    static int countdown = 10;
    if (countdown > 0)
    {
        --countdown;
        printf("countdown: %d!
", countdown);
    }
    else
    {
        longjmp(place, 1);
    }
}

int main(int argc, const char *argv[])
{
    lua_State* L = luaL_newstate();
    luaL_openlibs(L);
    lua_sethook(L, hook, LUA_MASKCOUNT, 100);

    if (setjmp(place) == 0)
        luaL_dostring(L, "function test() pcall(test) print 'recursing' end pcall(test)");

    lua_close(L);
    printf("Done!");
    return 0;
}
