Enumeration Type Documentation

enum imByteOrder
 

CPU Byte Orders.

Enumerator:
IM_LITTLEENDIAN  Little Endian - The most significant byte is on the right end of a word. Used by Intel processors.
IM_BIGENDIAN  Big Endian - The most significant byte is on the left end of a word. Used by Motorola processors, also is the network standard byte order. 
00212 {
00213   IM_LITTLEENDIAN, /**< Little Endian - The most significant byte is on the right end of a word. Used by Intel processors. */
00214   IM_BIGENDIAN     /**< Big Endian - The most significant byte is on the left end of a word. Used by Motorola processors, also is the network standard byte order. */
00215 };
