| Summary | 0000502: XSI semaphore maximum value | ||||
| Description | Section 4.16 states: For the semaphores associated with the X/Open System Interfaces (XSI) option, a semaphore is a positive integer (0 through 32767). However, at least the HP-UX 11i semvmx and Solaris 10 semsys:seminfo_semvmx tunable parameters can be set to allow semaphore values of up to 65535. | ||||
| Desired Action | Consider rewording the text to account for these different system-imposed limits. | ||||

There is no need for a change. Every implementation can differ. The standard only requires a minimum maximum. For compliance there only has to be one environment where the standard test suite is passed. |
|
|
Interpretation response ------------------------ The standard states that the maximum value for a semaphore is 32767, and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor. Rationale: ------------- 0 is not a positive integer, and some implementations supply a larger maximum value. Notes to the Editor (not part of this interpretation): ------------------------------------------------------- Implement changes in note 0000502:0000997. |

At line 3095, change: ... a semaphore is a positive integer (0 through 32767). to: ... a semaphore is an integer with minimum value 0 and an implementation-defined maximum value which shall be at least 32767. |
