* minor vfprintf and vfwprintf changes to please static code analyzersSzabolcs Nagy2013-10-071-4/+6
| | | | add missing va_end and remove some unnecessary code.
* removed unused variable in vfwprintfRich Felker2013-10-041-2/+1

* clean up stdio_impl.hRich Felker2012-11-081-0/+7
| | | | | | | | | | | this header evolved to facilitate the extremely lazy practice of omitting explicit includes of the necessary headers in individual stdio source files; not only was this sloppy, but it also increased build time. now, stdio_impl.h is only including the headers it needs for its own use; any further headers needed by source files are included directly where needed.
* use restrict everywhere it's required by c99 and/or posix 2008Rich Felker2012-09-061-1/+1
| | | | | | | | to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict.
* fix uninitialized var in vfwprintf printing 0-prec stringRich Felker2012-05-041-1/+1
| | | | this could lead to spurious failures of wide printf functions
* implement wprintf family of functionsRich Felker2011-03-171-0/+354
this implementation is extremely ugly and inefficient, but it avoids a good deal of code duplication and bloat. it may be cleaned up later to eliminate the remaining code duplication and some of the warts, but i don't really care about its performance. note that swprintf is not yet implemented.
