In a program you must write a parser program to examine the
/proc/interrupt file... maybe using regular expressions (see "man
regex" and regex.h in C).
Via kernel you can use the syscall kstat_irqs(IRQ_NUMBER) and, for
other information, see irb_desc array. But unfortunally these symols
are not exported by default.
---- a little (pseudo)example:
#include <linux/module.h>
#include <linux/interrupt.h>
#include <linux/irq.h>
#include <linux/kernel_stat.h>
static int mymodule_init(void)
{
printk(KERN_ALERT "irq%i:%i\n",
IRQ_NUMBER,
// irq_desc[IRQ_NUMBER].handler->typename,
kstat_irqs(IRQ_NUMBER));
return 0;
}
module_init(mymodule_init);
