How to call a C++ method from C? [duplicate]

Answer 1

If you want to do it correct

serial_comm_wrapper.h

#ifdef __cpluscplus
class MyClass;
extern "C" {
#else
struct MyClass;
typedef struct MyClass MyClass;
#endif

MyClass *MyClass_new();

void MyClass_sendCommandToSerialDevice(MyClass *instance, int Command, int Parameters, int DeviceId);

#ifdef __cpluscplus
}
#endif

serial_comm_wrapper.cc

#include "serial_comm_wrapper.h"
#include "serial_comm.hh"

MyClass *MyClass_new()
{
    return new MyClass();
}

void MyClass_sendCommandToSerialDevice(MyClass *instance, int Command, int Parameters, int DeviceId)
{
    instance->sendCommandToSerialDevice(command, Parameters, DeviceID);
}

external.c

#include "serial_comm_wrapper.h"

int main(int argc, char ** argv) {
     MyClass *instance = MyClass_new();
     MyClass_sendCommandToSerialDevice(instance, ...);
}
