您好：
在这段函数中的以下部分我不是很明白它的功能
if (MAX_CORE_VECTOR <= coreVector[core])
{
printf("Core %d Vector Number Exceed\n");
}
hintc[vector] = CSL_intcOpen (&intcObj[vector], event, (CSL_IntcParam*)&vector , NULL);
if (hintc[vector] == NULL)
{
printf("Error: GEM-INTC Open failed\n");
return -1;
}
/* Register an call-back handler which is invoked when the event occurs. */
EventRecord.handler = isr;
EventRecord.arg = 0;
if (CSL_intcPlugEventHandler(hintc[vector],&EventRecord) != CSL_SOK)
{
printf("Error: GEM-INTC Plug event handler failed\n");
return -1;
}
这三个IF语句的作用是什么？
