| Summary | 0001799: endian.h unconditionally requires 64-bit integers | ||||
| Description | Optional for stdint.h, but not endian.h. | ||||
| Desired Action | At the very location, change 8462 uint64_t htobe64(uint64_t); 8463 uint64_t htole64(uint64_t); 8464 uint64_t be64toh(uint64_t); 8465 uint64_t le64toh(uint64_t); 8466 The <endian.h> header shall define the uint16_t, uint32_t, and uint64_t types as described in 8467 <stdint.h>. accordingly. (Ie refer to "Integer types" of stdint.h.) On page 661, lines 23136-23139, change 23136 uint64_t htobe64(uint64_t host_64bits); 23137 uint64_t htole64(uint64_t host_64bits); 23138 uint64_t be64toh(uint64_t big_endian_64bits); 23139 uint64_t le64toh(uint64_t little_endian_64bits); in the same way, and on line 23151, change For each of the sizes 16, 32 and 64 to For each of the sizes 16 and 32, and if supported 64 | ||||

I forgot Page 1218, lines 41590 and 41593, where htobe64() and htole64() are unconditionally defined, Page 1328, line 44665, ditto le64toh(). Btw there is no be*toh() series in equal spirit to le*toh() on page 1328. |

Interpretation response ------------------------ The standard states that uint64_t is required to be defined by <endian.h> but is optional in <stdint.h>, and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor. Rationale: ------------- Since implementations need to support uint64_t in order to implement <endian.h>, there is no point in having it be optionally defined in <stdint.h>. For symmetry, int64_t should also be required in <stdint.h>. Notes to the Editor (not part of this interpretation): ------------------------------------------------------- On page 370 line 12947 section <stdint.h>, after: int32_tadd: int64_t On page 370 line 12950 section <stdint.h>, after: uint32_tadd: uint64_t Delete page 370 lines 12951-12965 |
