In Phil Cornes' book "The Linux A-Z", the declaration of request_irq is
int request_irq(unsigned int irq, void(*handler)(int), unsigned long type, char
*name);
I am using the Redhat Linux, 2.0.34, the declaration is not same as before.
By checking the source code, found it is:
int request_irq(unsigned int irq, void(*hander)(int, void*, struct pt_regs*),
unsinged long irqflags, const char* devname, void* dev_id);
Maybe the type equals the irqflags.
The question is:
What the pt_regs, dev_id represent? especially the dev_id.
I am eager for your help, thanks!
