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_t
add:
int64_t


On page 370 line 12950 section <stdint.h>, after:
uint32_t
add:
uint64_t


Delete page 370 lines 12951-12965
