---------------------------------------------------------------------- (0003786) shware_systems (reporter) - 2017-06-19 17:32 http://austingroupbugs.net/view.php?id=1151#c3786 ---------------------------------------------------------------------- Extensions to termios.h ======================= A new subsection named "The winsize_t structure" is added to the header termios.h right after the section "The termios structure." The type "unsigned short" follows historical convention. Perhaps the committee wishes to instead introduce appropriate integer types for the structure members instead. This might be useful for implementations aiming to support terminals with more than 65535 horizontal or vertical pixels. The winsize_t Structure --------------------- The <termios.h> header shall define the winsize_t structure, which shall include at least the following members: unsigned long ws_row rows, in characters. unsigned long ws_col columns, in characters. [XSI] or [UP] unsigned long ws_xpixel horizontal size, in pixels, if supported. unsigned long ws_ypixel vertical size, in pixels, if supported. [x] In all members named in this volume of POSIX.1 2008, a value of 0 shall indicate that the value is unknown. === Additional edits after as winsize an app reserved identifier, *_t standard reserved. Use of termios as a type identifier a grandfathered allowance. Changed to long as display arrays can have now over 65k chars or pixels easily enough with UHD 4k resolutions, yet be logically a single terminal. Option group added as base POSIX will still only require support for char array or line oriented devices, not pixel or vector based. This was part of Bug 1053 discussion. Moving any added support for vectors or pixels to the base is an Issue 9 matter. Errors for tcsetsize() is missing ENOSUP as a 'may fail' entry, also discussed, for terminals that have fixed dimensions. Believe additional text related to LINES and COLUMNS env. variables also desirable.
