* include: 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=326024
* Use __BSD_VISIBLE test instead checking for absense of _POSIX_SOURCE.Konstantin Belousov2017-05-241-4/+4
| | | | | | | | | | | | The Termios headers <termios.h> and <sys/_termios.h> used sometimes _POSIX_SOURCE directly to determine if a thing should be exposed to the user. This circumvented the feature mechanisms of <sys/cdefs.h>. Submitted by: Sebastian Huber <sebastian.huber@embedded-brains.de> MFC after: 2 weeks Notes: svn path=/head/; revision=318780
* include: Remove checks for __BSD_VISIBLE where redundant with __XSI_VISIBLEJilles Tjoelker2014-05-111-1/+1
| | | | | | | | | | | | or __POSIX_VISIBLE. Whenever <sys/cdefs.h> sets __BSD_VISIBLE to non-zero, it also sets __POSIX_VISIBLE and __XSI_VISIBLE to the newest version supported. No functional change is intended. Notes: svn path=/head/; revision=265878
* Add a new libc function: cfmakesane(3).Ed Schouten2010-11-021-0/+1
| | | | | | | | | | | | | | I've noticed various terminal emulators that need to obtain a sane default termios structure use very complex `hacks'. Even though POSIX doesn't provide any functionality for this, extend our termios API with cfmakesane(3), which is similar to the commonly supported cfmakeraw(3), except that it fills the termios structure with sane defaults. Change all code in our base system to use this function, instead of depending on <sys/ttydefaults.h> to provide TTYDEF_*. Notes: svn path=/head/; revision=214680

* Decompose <sys/termios.h>.Ed Schouten2009-11-281-0/+100
The <sys/termios.h> header file is hardlinked to <termios.h>. It contains both the structures and the flag definitions, but also the C library interface that's implemented by the C library. This header file has the typical problem of including too many random things and being badly ordered. Instead of trying to fix this, decompose it into two header files: - <sys/_termios.h>, which contains struct termios and the flags. - <termios.h>, which includes <sys/_termios.h> and contains the C library interface. This means userspace has to include <termios.h> for struct termios, while kernelspace code has to include <sys/tty.h>. Also add a <sys/termios.h>, which prints a warning message before including <termios.h>. I am aware that there are some applications that use this header file as well.
