| Summary | 0000097: per-thread dlerror strings | |||||||||||
| Description |
_____________________________________________________________________________ COMMENT Enhancement Request Number 27 peter:xxxxxxxxx Defect in XSH dlerror (rdvk# 1) {none} Mon, 9 Mar 2009 16:01:28 GMT _____________________________________________________________________________ The dlerror description can be read in such a way that per-thread dlerror strings are not allowed, see the discussion thread (http://www.opengroup.org/austin/mailarchives/ag/msg15415.html) [^] on the opengroup list for a variety of interpretations. A number of implementations from multiple vendors have thread specific errors, including: HP-UX, GNU/Linux with Glibc, Mac OS X, Tru64 Unix, z/OS. Information on most of these implementations was gathered with a small test program, however z/OS information was provided by its manual page: http://publib.boulder.ibm.com/infocenter/zos/v1r10/index.jsp?topic=/com.ibm.zos.r10.bpxbd00/dlerror.htm [^] The standard should reflect existing practice and should explicitly allow per-thread errors. |
|||||||||||
| Desired Action |
Change: The dlerror() function need not be thread-safe. To: The dlerror() function need not be thread-safe, however a thread-safe implementation may return only errors that occur on the current thread. |

Interpretation response ------------------------ The standard states the requirements for dlerror() strings and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor." Rationale: ------------- None. Notes to the Editor (not part of this interpretation): ------------------------------------------------------- Change: The dlerror() function need not be thread-safe. To: It is implementation-defined whether or not the dlerror() function is thread-safe. A thread-safe implementation shall return only errors that occur on the current thread. The APPLICATION USAGE on p730 24555-24560 will need changing Change from: may reside in a static buffer To: resides in a buffer that is either system wide or thread wide that may be overwritten on each call to dlerror() |
