12.1.1.3.2 Byte Operations on Integers

The byte-manipulation functions use objects called byte specifiers to designate the size and position of a specific byte within an integer. The representation of a byte specifier is implementation-dependent; it might or might not be a number. The function byte will construct a byte specifier, which various other byte-manipulation functions will accept.

The next figure shows defined names relating to manipulating bytes of numbers.
