Function Documentation

int endianess

(

void

)

determine endianess

Is this machine little endian

Returns:

0 for BIG_ENDIAN machines, 1 for LITTLE_ENDIAN mahcines

Determines if the host calling this routine is a big or little endian machine.

Returns:

A 0 for BIG_ENDIAN machines, 1 for LITTLE_ENDIAN mahcines.
