---------------------------------------------------------------------- (0006489) Don Cragun (manager) - 2023-09-25 16:13 https://www.austingroupbugs.net/view.php?id=1406#c6489 ---------------------------------------------------------------------- New text that allows both behaviours, as an Issue 8 compromise: Add a new paragraph after issue8 draft 3 P1617. L50906 (in open_memstream()) <blockquote>The <i>fseek</i>() and <i>fseeko</i>() functions can be used to set the file position beyond the current buffer length. It is implementation-defined whether this extends the buffer to the new length. If it extends the buffer, the added buffer contents shall be set to null bytes for <i>open_memstream</i>(), or null wide characters for <i>open_wmemstream</i>(); if it does not extend the buffer, then if data is later written at this point, the buffer contents in the gap shall be set to null bytes for <i>open_memstream</i>(), or null wide characters for <i>open_wmemstream</i>(). If <i>fseek</i>() or <i>fseeko</i>() is called with SEEK_END as the <i>whence</i> argument, it is implementation-defined whether the file position shall be adjusted either relative to the current buffer length or relative to the buffer size that would be set by an <i>fflush</i>() call made immediately before the <i>fseek</i>() or <i>fseeko</i>() call.</blockquote> Issue History Date Modified Username Field Change ====================================================================== 2020-09-28 21:26 djdelorie New Issue 2020-09-28 21:26 djdelorie Name => DJ Delorie 2020-09-28 21:26 djdelorie Organization => Red Hat Inc 2020-09-28 21:26 djdelorie Section => open_memstream 2020-09-28 21:26 djdelorie Page Number => https://pubs.opengroup.org/onlinepubs/9699919799/functions/open_memstream.html 2020-09-28 21:26 djdelorie Line Number => n/a 2020-09-29 06:22 Florian Weimer Issue Monitored: Florian Weimer 2020-09-29 17:53 carlos Note Added: 0005011 2020-09-29 20:54 Don Cragun Interp Status => --- 2020-09-29 20:54 Don Cragun Note Added: 0005012 2020-09-29 20:54 Don Cragun Category Base Definitions and Headers => System Interfaces 2020-09-29 20:55 Don Cragun Note Edited: 0005012 2020-09-29 20:55 Don Cragun Relationship added related to 0000456 2020-09-29 23:32 djdelorie Note Added: 0005013 2021-02-11 17:40 rhansen Note Added: 0005233 2021-02-11 18:43 shware_systems Note Added: 0005234 2021-02-11 18:43 shware_systems Note Added: 0005235 2021-02-11 18:43 shware_systems Note Deleted: 0005235 2023-09-25 16:13 Don Cragun Note Added: 0006489 ======================================================================
