Summary | 0000137: Can tempnam() use more than one i-d directory? | ||||
Description | The description of tempnam() states: "If dir is a null pointer or points to a string which is not a name for an appropriate directory, the path prefix defined as P_tmpdir in the <stdio.h> header shall be used. If that directory is not accessible, an implementation-defined directory may be used." The way this is worded carries an implication (although not a strong one) that there can only be one such implementation-defined directory. However, it seems likely that this was accidental rather than a deliberate intention to restrict tempnam() to one i-d directory. Some implementations try more than one additional directory if P_tmpdir is not accessible. This seems like a useful feature, and the wording should be clarified to explicitly allow it. | ||||
Desired Action | Change "an implementation-defined directory" to "one or more implementation-defined directories" (Note that in XSH7 this text is at page 2102 line 66520.) | ||||

Interpretation response ------------------------ The standard clearly state that this is implementation defined and conforming implementations must conform to this. Rationale: --------- "Implementation defined" permits the implementation to use any appropriate means to select an alternative directory, including selecting one entry from a list. The standards developers do not see any need to change the current wording; indeed, the proposed change suggests that an implementation might want to use multiple directories at the same time, which is not the intent. The implementation may pick one of a potentially infinite set of accessible directories. Notes to the Editor (not part of this interpretation): ------------------------------------------------------- Add mkdtemp() and mkstemp() to the See Also list. In the example (issue 7 lines 66534-66535) make the "directory" and "fileprefix" variables const. const char *directory = "/tmp"; const char *fileprefix = "file"; |
