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