- Subject: varargs
I have a printf() function written in C using va_start, va_arg, etc. It
works fine on i386. Lately, i needed it on my amd64 machine. However,
although it builds, it does not work.
After reading the x86_64 ABI, i found out that on amd64 each function's
args are moved to specific registers and not to the stack (like on i386).
Do i need to do something extra to use varargs functions on x86_64?
Thanks,
Constantine
PS I'm using gcc-4.1.3.
