Recommended Posts

in case anyone is interested, I translated the example Windows cli wrapper for the ESET API to Linux.

 

Compile and runs as follows. Note: All 3 shared libraries need to be in the same directory as the executable that get created. Limitation on how ESET created their shared libraries.

g++ -c -g -o esetapi_cli.o esetapi_cli.cpp && g++ esetapi_cli.o -L/usr/local/lib  -ldl -o esetapi


Source: esetapi_cli.cpp

#include <iostream>
#include <string>
#include <errno.h>
#include <dlfcn.h>

typedef int (*era_process_request)(const char* request, char** response);
typedef void (*era_free)(char* s);
typedef int (*era_init_lib)();
typedef void (*era_deinit_lib)();

int main(int argc, char** argv)
{

    // 1. Load library
    void* hMod = ::dlopen( "ServerApi.so", RTLD_LAZY | RTLD_GLOBAL );
    if (!hMod)
    {
        std::cout << "Cannot load api library error. Last error is: " << dlerror() << std::endl;
        return 1;
    }

    era_init_lib init_lib = (era_init_lib)::dlsym(hMod,"era_init_lib");
    if (!init_lib )

        std::cout<<"Cannot init library" << std::endl;
        ::dlclose(hMod);
        return 1;
    }

    // 7. Get pointer to function, which can deinitialize library

        deinit_lib();
        ::dlclose(hMod);
        return 1;
    }

    while (true)
    {
        std::string request;// = "{\"Era.ServerApi.StartRequest\":{}}";

            break;
