Valid values for pfnIntHandler?

[The_Meter413 0]

I'm playing with interrupts using my Tiva C series launchpad (chip is the TM4C123GH6PM), and the latest TivaWare version.  I'm reading through the API for registering interrupt handlers on a GPIO port, but I can't find some info: the function GPIOIntRegister takes as inputs a GPIO port base address, and a pointer to the interrupt handling functions.  Prototype is:

 
void
GPIOIntRegister(uint32_t ui32Port,
void (*pfnIntHandler)(void))

 

Where can I find valid values for pfnIntHandler?  The example code uses PortEIntHandler, so I'm pretty sure I can deduce what I would need to do to use, say, Port F, but it's bugging me that I can't find it when I dig through the documentation or the code.  Can anyone point me in the right direction?

 

Thx!

The value needs to be a pointer to a void function.

Check this example, it uses the interrupt handler register function:

Thanks for the clarification, and the link to the very handy/informative tutorial.

Check the rest if you are starting
I made them who is starting programming with Tiva. I have some updates I want to make but the time isn't enough for that.
Trying to get what's already there and adding more that's it's missing (like a more dedicated part to interrupts programming basis) more organized in a workshop stile.
