现在的中断处理函数的返回代码是一个 irqreturn_t类型。
The interrupt handler function now has a return code of type irqreturn_t.
最后详细地介绍了在QNX下驱动程序的开发包括中断处理函数的编写、系统硬件资源的管理以及驱动程序与测试程序的接口。
We also introduce the development of device driver under QNX, include programme of the interrupt handler, management of hardware resource and interface between application and device driver.
异常处理的最常见用法是中断一个函数，将异常提交给调用程序(可能是该调用程序，或者是堆栈中上级调用程序)。
The most common use of exception handling is breaking out of a function to raise an exception to a caller (which may be the caller or a caller higher up the stack).
然后该函数从中断的地方开始处理下一个被请求返回的值。
The function then picks up from where it left off the next time a value is requested.
程序中的信号处理程序捕获到函数的执行被某个信号中断，信号处理程序然后按正常方式返回。
EINTR — the function was interrupted by a signal, which was caught by a signal handler in the program, and the signal handler returned normally.
Oprofile是一种细粒度的工具，可以为指令集或者为函数、系统调用或中断处理例程收集采样。
OProfile is fine-grained and can collect samples for a set of instructions, or for function, system call, or interrupt handlers.
换句话说，控制单元在解决完中断信号后，处理的指令就是选中的处理函数的第一条指令。
In other words, the instruction processed by the control unit after dealing with the interrupt signal is the first instruction of the selected handler.
每一个中断是以一个被称为中断处理的函数调用来运行的，这些必须可以通过安装的设备驱动程序，根据设备被裁剪。
Every interrupt runs a function called an interrupt handler, which must be tailored to the device and therefore is installed by the device driver.
控制单元进行的最后一步等同于跳到中断或异常处理函数。
The last step performed by the control unit is equivalent to a jump to the interrupt or exception handler.
这个描述符指明了包含中断或异常处理函数的段的基地址。
This descriptor specifies the base address of the segment that includes the interrupt or exception handler.
这样特性用在很多中断处理函数，因为它容许串行地处理同一类型的IRQ。
This feature is used by most interrupt handlers, because it allows them to process IRQs of the same type serially.
这些值定义了中断或异常处理函数的第一条指令的逻辑地址。
These values define the logical address of the first instruction of the interrupt or exception handler.
