Hi Corey, (Sorry for the delay, I was out of town.) > How does the long long type change in 64-bit modes for C and C++? > > Does it stay 64-bit and is deprecated for long? My expectation is: int - natural word size of the architecture short - half the word size of the architecture long - twice the word size of the architecture long long - (if available at all) twice the size of long NOTE: my expectation differs from the C/C++ standard as the constraints of those data types. So for a 64-bit architecture: short - 32 bit int - 64 bit long - 128 bit long long - 256 bit That's my expectation. That's not what I'm seeing on the 64-bit platforms I work on. However, for me, an acceptable alternative is C99's <stdint.h>. --Eljay
