int beieeeftoa32(char *a, uint n, void *f)
u16int beload2(uchar *p)
u16int leswap2(u16int u)

int ieeeftoa32(char *a, uint n, u32int u)
DESCRIPTIONThese 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. SOURCE/src/libmachSEE ALSO Visit the GSP FreeBSD Man Page Interface. |
