PIC的中断服务程序“不允许使用不完整的类型”

Question

When I try to compile the code for a PIC program using PICMicro C compiler, I got the error "incomplete type is not allowed" for the interrupt service routine part of the code:

char chB = 0;
int clicks = 0;
void interrupt ISR(void) //incomplete type is not allowed
{
    if(RBIF == 1)
    {
        clicks++;
        chB = PORTB;
        RBIF = 0;
    }
}

After checking multiple sources, I still do not see how the service routine is incorrectly written..

Edit: Thanks for all your help, I have found the solution:

char chB = 0;
int clicks = 0;
#pragma vector = 0x04
__interrupt void isr(void)
{
    if(RBIF == 1)
    {
        clicks++;
        chB = PORTB;
        RBIF = 0;
    }
}

Answer 1

"interrupt ISR" is not a valid name, because it has a space in it. void interrupt_isr(void) should be fine.

Answer 2

For PIC16xxx family MCUs use this form:

void interrupt () {

  } // end interrupt
