获取程序名

/home/kelsel/a.out
=>得到a.out

void strrchr_test(int argc, char **argv)
{
    char *name = NULL;
    if ( argc > 0 )
    {
        if ((name = strrchr(argv[0], '/')) == 0)/* name = /a.out */
        {
            name = argv[0];
        }
        else
        {
            name++; /* name = a.out */
        }
    }
    if ( name != NULL )
    {
        puts(name);
    }
}
