* Revert "Don't overread or write memory returned by _DTOA_R"Corinna Vinschen2017-06-191-13/+12

* Don't overread or write memory returned by _DTOA_RSilviu Baranga2017-06-091-12/+13
| | | | | | | | | | | | | | | Don't over-read memory returned by _DTOA_R, and never write to it since the result might be a string literal. For example, when doing: swprintf(tt, 20, L"%.*f", 6, 0.0); we will get back "0". Instead, write the result returned by _DTOA_R to the output buffer. After this, write the 0 chars directly to the the output buffer (if there are any). This also has the (marginal) advantage that we read/write less memory overall.

* POSIX-1.2008 per-thread locales, groundwork part 2Corinna Vinschen2016-08-151-1/+1
| | | | | | | | | Move all locale category structure definitions into setlocale.h and remove other headers in locale subdir. Create inline accessor functions for current category struct pointers and use throughout. Use pointers to "C" locale category structs by default in __global_locale.
