Hi, In i8259.c, there is an odd funciton definition as follows: asmlinkage void IRQ0x01_interrupt(); __asm__( ...); I have no idea of this kind of definition. Is it a grammer extention of gcc, or facilities of standard C that I don't know? -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
