问题描述

除了Mutex是Binary还是Semaphore是计数器之外，WinCE中的Mutex和Semaphore之间是否存在任何差异？优先级继承不适用于信号量，信号量没有与之关联的特定所有者。

这是什么概念？我要求两名司机使用相同的tranceiver。因此，当任何应用程序关闭一个驱动程序时，我想检查其他驱动程序是否需要它。对于这个要求我可以使用信号量还是只需要使用互斥量？

问候，

Hi,

Are there any differences between Mutex and Semaphore in WinCE apart from Mutex is Binary and Semaphore is a counting one? and Priority inheritance does not apply to semaphores, which do not have a specific owner associated with them.

What is this owner concept? I have a requirement that two drivers are using the same tranceiver. So, while any application closes one driver I want to check if the other driver need it. For this requirement can I use Semaphore or do I need to use Mutex only?

Regards,

GSR
