big endian to little endian

[blackmen]

Hi all,

i am using Intel C Compiler for 32-bit applications, Version 9.0 for compiling c and c++ program ....

i am having binary file which is having big endian formatted data ......

how to convert this big endian to little endian format ?.....

Thanking you.

Is this by chance on a Mac?

If this is for a Mac, you should be using the 9.1 compiler, and I would refer you to http://developer.apple.com/documentation/MacOSX/Conceptual/universal_binary/

for more details on byte-swapping to account for endian-ness.

If not, perhaps you could provide a little more detail as to the problem you're trying to solve?

Thanks!

By using bswap assembler instruction (i.e. bswap eax) or equivalent compiler intrinsic if available.

Note that there is no SIMD instruction for that purpose although it would be very usefull for sound card (wave) drivers.
