* fix erroneous stop before input limit in mbsnrtowcs and wcsnrtombsRich Felker2017-08-311-1/+3
| | | | | | | | | | the value computed as an output limit that bounds the amount of input consumed below the input limit was incorrectly being used as the actual amount of input consumed. instead, compute the actual amount of input consumed as a difference of pointers before and after the conversion. patch by Mikhail Kremnyov.
* remove comments on copyright status from UTF-8 implementation filesRich Felker2016-06-211-6/+0
| | | | | | | | despite clarifications made to the COPYRIGHT file in commit f0a61399330bae42beeb27d6ecd05570b3382a60, there continues to be confusion about whether the permissions granted actually apply to all files. I am the sole author of these files and clearly intend, and have always intended, for the grant of permission to apply to them.
* fix return value computation in one code path of wcsnrtombsRich Felker2014-12-181-1/+1
| | | | the affected code was wrongly counting characters instead of bytes.
* include cleanups: remove unused headers and add feature test macrosSzabolcs Nagy2013-12-121-5/+0

* 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 longstanding exit logic bugs in mbsnrtowcs and wcsnrtombsRich Felker2012-05-021-4/+5
| | | | | | | | these are POSIX 2008 (previously GNU extension) functions that are rarely used. apparently they had never been tested before, since the end-of-string logic was completely missing. mbsnrtowcs is used by modern versions of bash for its glob implementation, and and this bug was causing tab completion to hang in an infinite loop.
* initial check-in, version 0.5.0 v0.5.0Rich Felker2011-02-121-0/+51
