pmcraid_unre...rupt_handler(9)
π pmcraid_unre...rupt_handler(9) β like, the Kernel API Manual, bestie π
okay so this is the page for pmcraid_unregister_interrupt_handler(9), straight out of the Kernel API Manual, and tbh it's short but it matters. It's the breakup routine. The "we're done here, pack your stuff" moment for interrupt handlers. Let's get into it β¨
β¨ NAME β¨
pmcraid_unregister_interrupt_handler β de-registers interrupt handlers π«Ά (yes that's the whole vibe: it un-registers them, it does not register them, do not get it twisted π)
πΈ SYNOPSIS πΈ
void pmcraid_unregister_interrupt_handler (struct pmcraid_instance
*pinstance );
literally that's it. one function, one argument, returns void. minimal. clean. iconic. π
π¦ ARGUMENTS π¦
pinstanceβ pointer to the adapter instance structure. like, the actual adapter's little ID card πͺͺ β you hand it over and the routine knows exactly which one you mean.
π DESCRIPTION π
okay so here's the tea β: this routine un-registers a registered interrupt handler, and on top of that it also frees the irqs/vectors. so it's not just "see ya" β it's "see ya and I'm taking my stuff back." no cap. π₯
Return Value: None. that's it. nothing comes back. it's giving "I don't owe you an explanation" energy π
π SEE ALSO π
