L3TOL(3)						     Library Functions Manual							  L3TOL(3)

l3tol, ltol3 - convert between 3-byte and long integers (2BSD) SYNOPSIS
l3tol(lp, cp, n) long *lp; char *cp; ltol3(cp, lp, n) char *cp; long *lp; DESCRIPTION
L3tol converts a list of n three-byte integers packed into a character string pointed to by cp into a list of long integers pointed to by lp. Ltol3 performs the inverse conversion from long integers (lp) to three-byte integers (cp). These functions are useful for file-system maintenance under 2BSD where disk addresses within inodes are three bytes long. SEE ALSO
fs(5) BUGS
l3tol and ltol3 are unique to the PDP-11 and 2BSD; their use is discouraged. 3rd Berkeley Distribution L3TOL(3)

BYTEORDER(3)						   BSD Library Functions Manual 					      BYTEORDER(3)

htonl, htons, ntohl, ntohs -- convert values between host and network byte order LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <arpa/inet.h> uint32_t htonl(uint32_t host32); uint16_t htons(uint16_t host16); uint32_t ntohl(uint32_t net32); uint16_t ntohs(uint16_t net16); DESCRIPTION
These routines convert 16 and 32 bit quantities between network byte order and host byte order. On machines which have a byte order which is the same as the network order, these routines are defined as macros that expand to the value of their argument. These routines are most often used in conjunction with Internet addresses and ports as returned by gethostbyname(3) and getservent(3). SEE ALSO
bswap(3), gethostbyname(3), getservent(3) STANDARDS
The described functions conform to IEEE Std 1003.1-2001 (``POSIX.1''). HISTORY
The byteorder functions appeared in 4.2BSD. BUGS
The `l' and `s' suffixes in the names are not meaningful in machines where long integers are not 32 bits. BSD
