* libc: provide fputc_unlockedKyle Evans2020-02-021-0/+1
| | | | | | | | | | | | | | Among the same justification as the other stdio _unlocked; in addition to an inline version in <stdio.h>, we must provide a function in libc as well for the functionality. This fixes the lang/gcc* builds, which want to use the symbol from libc.

* stdio: provide _unlocked variants of fflush, fputc, fputs, fread, fwriteKyle Evans2020-01-301-1/+7
| | | | | | | | | | | | | | | | fflush_unlocked is currently desired in ports by sysutils/metalog, and redefined as the locked fflush. fputc_unlocked, fputs_unlocked, fread_unlocked, and fwrite_unlocked are currently desired in ports by devel/elfutils, and redefined as the locked fputs, fread, and fwrite respectively.

Leave it in the existing symbol version so anything that previously linked aginst it still runs, but do not allow new software to link against it.

* 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

The replacement should be transparent for clang developers as the new qualifiers will produce the same warnings and will be useful for static checkers but will not cause aggressive optimizations.

Some notes: - Where possible I restored the various lines to their pre-__sFILEX state. - Retire INITEXTRA() and just initialize the wchar bits (orientation and mbstate) explicitly instead. The various places that used INITEXTRA didn't need the locking fields or _up initialized. (Some places needed _up to exist and not be off the end of a NULL or garbage pointer, but they didn't require it to be initialized to a specific value.) - For now, stdio.h "knows" that pthread_t is a 'struct pthread *' to avoid namespace pollution of including all the pthread types in stdio.h. Once we remove all the inlines and make __sFILE private it can go back to using pthread_t, etc. - This does not remove any of the inlines currently and does not change any of the public ABI of 'FILE'.
