Call Library Function -> PID

[thenoob94]

I've written a c Function and compiled it to a shared object. I call the function in labview and it executes just fine. The function modifies a ".cti" file. When I want to execute the function a second time it fails because labview still takes ownership of the process even after it terminates. When I run the function without labview this error doesn't occur..

 

This is my function:

extern "C"{
    int InitSDK();
}

int InitSDK()
{
    string ctiPath;
    string genicamPath;
    string genicamCachePath;
    string clProtocolPath;

#if defined (WIN32)

    char buffer[1024] = { 0 };
    int res = GetEnvironmentVariableA("GENICAM_GENTL64_PATH", buffer, sizeof(buffer));
    if (0 == res)
        return false;

    ctiPath = string(buffer);

    memset(buffer, 0, sizeof(buffer));
    res = GetEnvironmentVariableA("SVS_GENICAM_ROOT", buffer, sizeof(buffer));
    if (0 == res)
        return false;

    genicamPath = string(buffer);

    memset(buffer, 0, sizeof(buffer));
    res = GetEnvironmentVariableA("SVS_GENICAM_CACHE", buffer, sizeof(buffer));
    if (0 == res)
        return false;

    genicamCachePath = string(buffer);

    memset(buffer, 0, sizeof(buffer));
    res = GetEnvironmentVariableA("SVS_GENICAM_CLPROTOCOL", buffer, sizeof(buffer));
    if (0 == res)
        return false;

    clProtocolPath = string(buffer);

    SV_RETURN ret = SVLibInit(ctiPath.c_str(), genicamPath.c_str(), genicamCachePath.c_str(), clProtocolPath.c_str());
#elif defined(__linux__)
    ctiPath ="./";
    SV_RETURN ret = SVLibInit(ctiPath.c_str(), NULL, NULL, NULL);

#elif defined(__APPLE__) && defined(__MACH__)
    ctiPath = "/Library/Frameworks/SVGenSDK.framework/Versions/2.5.8/Libraries/cti";
    SV_RETURN ret = SVLibInit(ctiPath.c_str(), NULL, NULL, NULL);
#endif
    if (SV_ERROR_SUCCESS != ret)
    {
        printf("SVLibInit Failed! :%d", ret);
        return -1;
    }
    
    printf("Init worked \n");
    return 0;
}
