libc: remove explicit cast NULL in atoi

2018-06-13T08:52:17+00:00

There isn't any reason to cast NULL so just remove it. Noticed when
cleaning up top.

General further adoption of SPDX licensing ID tags.

2017-11-20T19:49:47+00:00

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.

Use ANSI C prototypes. Eliminates -Wold-style-definition warnings.

Renumber clauses to reduce diffs to other versions

NetBSD, OpenBSD, and Android's Bionic number the clauses 1 through 3,
so follow suit to make comparison easier.

Implement xlocale APIs from Darwin, mainly for use by libc++. This adds a

load of _l suffixed versions of various standard library functions that use
the global locale, making them take an explicit locale parameter.  Also
adds support for per-thread locales.  This work was funded by the FreeBSD
Foundation.

Please test any code you have that uses the C standard locale functions!

Back out errno preserving

2001-12-30T03:34:46+00:00

Preserve errno.

2001-12-25T04:10:50+00:00

According to C99:
"The  functions  atof,  atoi,  atol, and atoll need not
affect the value of  the  integer  expression  errno  on  an
error.   If  the  value of the result cannot be represented,
the behavior is undefined."
