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, respec-
tively.
MACH-SWAP(3) MACH-SWAP(3)
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.
