libc __sfvwrite(): roll back FILE buffer pointer on fflush error

2022-03-14T14:10:37Z

__sfvwrite() advances the pointer before calling fflush. If fflush() fails, it is not enough to roll back inside it, because we cannot know how much was advanced by the caller.

General further adoption of SPDX licensing ID tags.

2017-11-20T19:49:47Z

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.

Rename cantwrite() to prepwrite(). The latter is less confusing,

since the macro isn't really a predicate, and it has side-effects. Also, don't set errno if prepwrite() fails, since this is done in prepwrite() now.

If handed a file pointer we can't write to, set errno properly to EBADF
