| Summary | 0001244: ident string lifetime not specified | ||||
| Description | It's not stated that the ident string value may be used directly and therefore must remain valid after the call to openlog (until the next openlog?). Most implementations I've checked seem to use it directly--glibc 2.29, OpenBSD 6.4, and (per man page) Solaris 11.4. At least one makes a copy--musl libc 1.1.21 (silently truncating). This came to my attention when writing bindings for a scripting language. | ||||
| Desired Action | Amend to explicitly state that the lifetime of the ident string object must persist for the lifetime of the process or until (immediately after?) the next call to openlog. | ||||

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: ------------- None. Notes to the Editor (not part of this interpretation): ------------------------------------------------------- On page 695 line 23775 section closelog(), change: The ident argument is a string that is prepended to every message.to: The ident argument is a pointer to a null-terminated identifier that shall be prepended (without the null terminator) to every message. The application shall ensure that the string pointed to by ident remains valid during the syslog() calls that will prepend this identifier; however, it is unspecified whether changes made to the string will change the identifier prepended by later syslog() calls. |
