so i try to implment a little handler for some eception : -asm file :

;exception whiech have error
exception_handler :
    pop eax ; take the error code
    push eax
    call exception ; call C function which take error code in parameter
    pop eax ;remove error code
    iret

C file :

void exception(int _error_code_)
{
    if ( (_error_code_ & 0x1) == 0x0);
        //external event didn't occur
    else if ((_error_code_ & 0x1) == 0x1);
        //External error occur
    else  ;   
}

SO my preocupation is that , i don't know how i can implement exception handler
