| Summary | 0000360: ctermid should be optional in <unistd.h> | ||||
| Description | The standard is explicit that ctermid( ) is required to live in <stdio.h> and is an extension to the C standard, as seen in both XBD <stdio.h> line 11819 and in XSH termid SYOPSIS at line 24006. The standard also mentions that <unistd.h> must declare ctermid(); however, this does not match existing practice. On at least FreeBSD, ctermid( ) is not declared in <unistd.h>, but lives only in <stdio.h>. However, the cat is already out of the bag for namespace pollution, as at least glibc and Solaris declare ctermid( ) in both headers, so we must continue to permit this. [I noticed this issue because the ctermid( ) declaration was the only CX shaded line in <unistd.h>, but since that entire header is not mandated by C, it should not need any CX shading; deleting the problematic line happens to also solve the shading issue.] | ||||
| Desired Action | Delete line 15048 (ctermid declaration in XBD <unistd.h>). At line 15124 (<unistd.h>), add a sentence: Implementations may also include the ctermid( ) prototype as defined in <stdio.h>. | ||||

Interpretation response ------------------------ The standard states that <unistd.h> shall include a function prototype for ctermid(), and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor. Rationale: ------------- Some implementations have had a declaration for ctermid() and this should still be allowed in Issue 7. Having ctermid() and pthread_atfork() prototypes in <unistd.h>, however, are namespace pollution issues that should be corrected in the next revision. Notes to the Editor (not part of this interpretation): ------------------------------------------------------- Delete line 15048 (ctermid declaration in XBD <unistd.h>). At line 15124 (<unistd.h>), add a sentence: Implementations may also include the ctermid( ) prototype as defined in <stdio.h>. Tag the entire paragraph starting on line 15124 including the above new sentence with the OB margin marking. |
