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. + +
