` `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.
