Endianess is byte ordering not bit

Hi David,
This might be an unusual question because mysql always stores in little
endian for all platforms (if I'm not mistaken). However, I am receiving
data from several different platforms (custom boards with various
processors) in raw form. I will have stored as a configuration option
If I do it in C I need to do a user-defined function correct?
Anyway, I am infact storing the data raw. Unfortunately byte swapping
before is not an option because I am getting a stream of raw data and
storing it in a blob field. Then based on some configuration, I pull
parts of the data out
