Hello,
Generally request_irq is used to enable a device driver (or other
handler) to be associated with a hard interrupt. The function is defined
in (for i386 architecture) <source-path>/linux/arch/i386/kernel/irq.c .
It is declared in /usr/include/linux/sched.h .
If the handler you are writing is to built into the kernel, then you
shouldn't have any problem. If you are going to use it as a loadable
module, then insmod should take care of the dependencies, using the kernel
public symbol table (look at /proc/ksyms). Loadable modules aren't
"linked" ; insmod essentially does this when loading. If you are trying to
write a user-land app to do interrupt handling, you may strongly want to
consider breaking it up to include a kernel-space (loadable) module and a
user-space application communicating with it.
Hope this helps.
George
