Calling a ros service function from another one

edit

I am trying to find a way to call a service function from another one. To explain the situation, let's assume the following ROS messages and services:

# mypack/msg/MyRosMsg.msg
uint8       v1
# ... other definitions

# mypack/srv/MyRosSrv1.srv
mypack/MyRosMsg  msg

# mypack/srv/MyRosSrv2.srv
mypack/MyRosMsg  msg
# ... other definitions

I have a ROS service function as below:

bool my_service_1(mypack::MyRosSrv1::Request &req, mypack::MyRosSrv1::Response &req)
{
  // do some processing
  return(true);
}

and I want to call my_service_1 from the second service function by copying msg member of MyRosSrv2 into MyRosSrv1 as below:

bool my_service_2(mypack::MyRosSrv2::Request &req, mypack::MyRosSrv2::Response &req)
{      
  mypack::MyRosSrv1 srv1;
  srv1.msg = req.msg;
  // how to call properly my_service_1?
}

Edit 1 Both service functions are inside one node. The service my_service_1 performs a processing that I am trying to avoid repeating the code in the service my_service_2.

Edit 2 As tbh answered, the following changes is the trick to make it work:

bool my_service_2(mypack::MyRosSrv2::Request &req, mypack::MyRosSrv2::Response &req)
{      
  mypack::MyRosSrv1 srv1;
  srv1.request.msg = req.msg;
  my_service_1(srv1.request, srv1.response);
  // do other processing
}
