如何在linux中从静态加载的库中执行函数?

JNI_CreateJavaVM() 通过函数指针,这样我就可以启动可执行文件而无需首先设置 LD_LIBRARY_PATH

到目前为止,我已经知道了如何编译和链接它,但我正在努力解决声明函数指针然后稍后执行函数的语法问题:

JavaVM *jvm;
JNIEnv *env;
JavaVMInitArgs vm_args;
JavaVMOption* options = new JavaVMOption[10];

...

std::string location = "./jre/lib/server/libjvm.so";
void *handle = dlopen ( location.c_str(), RTLD_LAZY );

if ( !handle ) {
   printf ( "Unable to load %s, exiting", location.c_str() );
   return 0;
}

?? = dlsym ( handle, "JNI_CreateJavaVM" ); //get the function pointer

//This is how I would execute the function if dynamically linking: 
//JNI_CreateJavaVM( &jvm, (void**)&env, &vm_args );

?? ( &jvm, (void**)&env, &vm_args ); //Execute the function pointer. 

?? 谁来做这件事?我已经试过了 dlsym documentation ,但我对C/C++太不熟悉,无法将其转换为我的情况。

谢谢
