* warnx: fix needless staticWarner Losh2020-10-241-2/+2
| | | | | | | | | I noticed after the review that these shouldn't be static. Remove the 'static' from them, otherwise concurrent calls to warn* might see a similar but to the original. Notes: svn path=/head/; revision=366983
* warnx: Save errno across calls that might change it.Warner Losh2020-10-231-0/+8
| | | | | | | | | | | | | | | When warn() family of functions is being used after err_set_file() has been set to, for example, /dev/null, errno is being clobbered, rendering it unreliable after, for example, procstat_getpathname() when it is supposed to emit a warning. Then the errno is changed to Inappropriate ioctl for device, destroying the original value (via calls to fprintf()functions).

* Clean up the vcs ID strings in libc's gen/ directory.John Baldwin2018-07-031-3/+1
| | | | | | | | | | | | | | | | | | | | - Move CSRG IDs into __SCCSID(). - When a file has been copied, consistently use 'From: <tag>' for strings referencing the version of the source file copied from in the license block comment. - Some of the 'From:' tags were using $FreeBSD$ that was being expanded on each checkout. Fix those to hardcode the FreeBSD tag from the file that was copied at the time of the copy. - When multiple strings are present list them in "chronological" order, so CSRG (__SCCSID) before FreeBSD (__FBSDID). If a file came from OtherBSD and contains a CSRG ID from the OtherBSD file, use the order CSRG -> OtherBSD -> FreeBSD.

* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025
* err(3): use `NULL`, aka `(void*)0` per POSIX instead of `(FILE *)0`Enji Cooper2017-05-231-4/+4

* Renumber copyright clause 4Warner Losh2017-02-281-1/+1
| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

| | | | | | | | | Also, make an internal _getprogname() that is used only inside libc. For libc, getprogname(3) is a weak symbol in case a function of the same name is defined in userland. Notes: svn path=/head/; revision=93399

* A small last-minute iitem for 3.0:Garrett Wollman1998-09-121-75/+67
| | | | | | | | | | | | - Fix some style errors I made back in 1995. - Add a new flavor of the err(3) family, which takes an explicit errno argument rather than implicitly examining errno. This will make it easier to use these functions in conjunction with modern library interfaces that return an errno value explicitly. Notes: svn path=/head/; revision=39112
