Interpretation Request #8
Topic: ftruncate Relevant Sections: 188.8.131.52 lines 1017-1018
This section states "The ftruncate() function marks the st_ctime and st_mtime fields of the file." Other interfaces such as write() have similar but different wording: ".. shall mark for update the st_ctime ... fields of the file." Are these phrases "marks the ... fields of the file" and "shall mark for update.." equivalent?
The meaning of the phases is the same. This is an editorial oversight and the committee has requested that the project editor change the first occurance to "...shall mark for update.." in section 184.108.40.206 line 1017.
