| Summary | 0001987: The option value type for TCP_NODELAY is not specified. | ||||
| Description | The option value type for TCP_NODELAY is not specified. This seem to be the case since at least Issue 6. Many other options have types of rank `int`, and their Windows counterparts often have DWORD or similar, as such I believe the type for this option value is most likely also `int`, rather than `_Bool` which may have issue with ABI compatibility. | ||||
| Desired Action | Clarify that the option value type for TCP_NODELAY is `int`. | ||||

Interpretation response ------------------------ The standard is unclear on this issue, and no conformance distinction can be made between alternative implementations based on this. This is being referred to the sponsor. Rationale: ------------- As described, the value is unspecified, with no definitive definition at this time. This will be pursued in the next edition. Notes to the Editor (not part of this interpretation): ------------------------------------------------------- On page 323, after line 11353, add the following line: The value associated with TCP_NODELAY shall have an integer type with the rank of int, acting as a flag with either a zero (unset) or non-zero (set) value. |

Re https://www.austingroupbugs.net/view.php?id=1987#c7446 > TCP_NODELAY shall be of __integer__ rank You mean "shall be of rank `int`"? |
|
|
According to my research: In the C standard, integer conversion rank is a property of a type, not of a value Alternate proposal: The value associated with TCP_NODELAY shall have an integer type with the rank of int, acting as a flag with either a zero (unset) or non-zero (set) value. |
