  • C2X Liaison: Removal of Deprecated Functions Title: Removal of Deprecated Functions Author: Nick Stoughton / the Austin Group Date: 2020-08-17
    ISO/IEC JTC 1/SC 22/WG 14 Nxxxx Austin Group Document 1056 C2X Liaison: Removal of Deprecated Functions Title: Removal of Deprecated Functions Author: Nick Stoughton / The Austin Group Date: 2020-08-17 As stated in N2528, The Austin Group is currently in the process of revising the POSIX (ISO/IEC Std 9945), and is trying to keep aligned with C17 and C2X changes as necessary. There are several functions that are marked as "Obsolescent" in the current version of the POSIX standard that we would typically remove during this revision process. However, we note that in the current working draft for C2X the two obsolete functions "asctime_r()" and "ctime_r()" have been added. During the August 2020 WG 14 meeting, there was general agreement to seek a paper that more closely aligned the C2X functions with POSIX, noting that it was at very least odd that C2X should be adding functions already marked as obsolete. However, there was also concern that strftime, the proposed alternative to use for these new “asctime_r()” and “ctime_r()” , would “pull in locale baggage not wanted in small embedded programs”. Locale Free Alternatives It should be noted that asctime_r() is currently defined to be equivalent to a simple snprintf() call, and anyone who really wants a locale free way to print the date and time could use this. As an experiment, three equivalent simple programs were constructed: date1.c #include <stdio.h> #include <time.h> char * date1(const struct tm * timeptr , char * buf) { static const char wday_name[7][3] = { "Sun", "Mon", "Tue", "Wed",

However, today's hardware land- 10% serial scape is very different, and moving in directions that make 0.1% serial database machines increasingly attractive.

  • C2x Proposal
    Proposal for C2X WG14 N2475 Title: Why no wide string strfrom functions Author, affiliation: C FP group Date: 2019-12-30 Proposal category: Editorial Reference: N2400, N2433 ISO/IEC 9899 working draft Problem: There are wide string analogs for the strtod function family, but not the strfromd family. It would be helpful to say how to easily achieve conversions to wide strings, and hence why additional functions to do the job are not provided. N2400 suggested adding a paragraph in 7.29.4.1. At its fall 2019 meeting, WG14 requested this be redone as a footnote with a recipe for wide string analogs of strfromd. Where would be a good place to attach the footnote? It pertains specifically to 7.29.4.1, but there is no text there, and footnotes aren’t attached to subclause titles (that we see). The suggested change below adds an introductory sentence in 7.29.4.1 and attaches the footnote to the new text. Note that other subclauses of 7.29.4 don’t reference the single- byte versions this way. We also considered attaching the footnote to the first sentence of 7.29.4, but that seemed less helpful to the reader. Suggested change: In 7.29.4.1, insert the paragraph: [1] This subclause describes wide string analogs of the strtod family of functions (7.22.1.5, 7.22.1.6). In 7.29.4.1, attach a footnote to the wording: the strtod family of functions (7.22.1.5, 7.22.1.6) where the footnote is: [1] Wide string analogs of the strfromd family of functions.
