-.fi
-.SH DESCRIPTION
-These functions return a value in which the order of the bytes
-in their 2-, 4-, or 8-byte arguments is reversed.
-.SH RETURN VALUE
-These functions return the value of their argument with the bytes reversed.
-.SH ERRORS
-These functions always succeed.
-.SH STANDARDS
-GNU.
-.SH EXAMPLES
-The program below swaps the bytes of the 8-byte integer supplied as
-its command-line argument.
-The following shell session demonstrates the use of the program:
