问在C程序中如何控制execl()调用后父进程的执行？

EN

int main()
{
    int iExecRetVal, pid;
    pid = fork();

    if (pid == -1)
    {

    }
    else if (pid > 0)
    {
    }
    else
    {
        iExecRetVal = execl("./flute-static", "./flute-static", "-send", "-a192.168.190.1/6666", "JFlute.1.2.tar.gz", NULL);
        if (iExecRetVal == -1)
        {
            /*execl() failed, need some error handling in the parent process*/
        }
        _exit(0);
    }

    /*Parent's normal execution*/
}

int HandleSuccessFromParent()
{
    /*Should be called when exec call was successful*/
}

int HandleFailureFromParent()
{
    /*Should be called when exec call was NOT successful*/
}
