SYNOPSIS

#include <u.h> #include <libc.h> #include <mach.h> u16int beswap2(u16int u) u32int    beswap4(u32int u) u64int    beswap8(u64int u) int     beieeeftoa32(char *a, uint n, void *f) int      beieeeftoa64(char *a, uint n, void *f) int      beieeeftoa80(char *a, uint n, void *f) u16int beload2(uchar *p) u32int    beload4(uchar *p) u64int    beload8(uchar *p) u16int leswap2(u16int u) u32int    leswap4(u32int u) u64int    leswap8(u64int u) int     leieeeftoa32(char *a, uint n, void *f) int      leieeeftoa64(char *a, uint n, void *f) int      leieeeftoa80(char *a, uint n, void *f) u16int leload2(uchar *p) u32int    leload4(uchar *p) u64int    leload8(uchar *p) int     ieeeftoa32(char *a, uint n, u32int u) int      ieeeftoa64(char *a, uint n, u32int hi, u32int lo)

DESCRIPTION

These functions provide machine-independent access to data in a particular byte order. Beswap2, beswap4, and beswap8 return the 2-byte, 4-byte, and 8-byte big-endian representation of the bytes in val, respectively. Beload2, beload4, and beload8 return the 2-byte, 4-byte, and 8-byte big-endian interpretation of the bytes at p, respectively. Beieeeftoa32, beieeeftoa64, and beieeeftoa80 format the big-endian 4-byte, 8-byte, or 10-byte IEEE floating-point value at f into the n-byte string buffer a. Leswap2, leswap4, etc. are the little-endian equivalents of the routines just described. Ieeeftoa32 and ieeeftoa64 format a local machine byte-order floating-point value into the n-byte string buffer a. Ieeeftoa32 expects a 32-bit floating-point value stored in the bits of u. Ieeeftoa64 expects a 64-bit floating-point value whose high 32-bits are in hi and low 32-bits are in lo.
