https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=199472 --- Comment #1 from commit-hook@freebsd.org --- A commit references this bug: Author: jhb Date: Mon May 4 14:47:00 UTC 2015 New revision: 282417 URL: https://svnweb.freebsd.org/changeset/base/282417 Log: Various updates to the ftruncate(2) documentation: - Note that ftruncate(2) can operate on shared memory objects and cross reference shm_open(2). - Note that ftruncate(2) does not change the file position pointer (aka seek pointer) of the file descriptor. - ftruncate(2) will fail with EINVAL for all sorts of other fd types than just sockets, so instead note that it fails for all but regular files and shared memory objects. - Note that ftruncate(2) also appeared in 4.2BSD along with truncate(2). (Or at least the manpage for both appeared in 4.2, I did not check the kernel code itself to see if either predated 4.2.) PR: 199472 (2) Submitted by: andrew@ugh.net.au (2) MFC after: 1 week Changes: head/lib/libc/sys/truncate.2 -- You are receiving this mail because: You are the assignee for the bug.
