* $Log$
* Revision 1.4 2003/02/22 21:57:03 oetiker
* a patch to avoid a memory leak and a Makefile.am patch to
* distribute all required source files -- Peter Stamfest <[email protected]>
*
* Revision 1.3 2003/02/13 07:05:27 oetiker
* Find attached the patch I promised to send to you. Please note that there
* are three new source files (src/rrd_is_thread_safe.h, src/rrd_thread_safe.c
* and src/rrd_not_thread_safe.c) and the introduction of librrd_th. This
* library is identical to librrd, but it contains support code for per-thread
* global variables currently used for error information only. This is similar
* to how errno per-thread variables are implemented. librrd_th must be linked
* alongside of libpthred
*
* There is also a new file "THREADS", holding some documentation.
*
* -- Peter Stamfest <[email protected]>
*
* Revision 1.2 2002/02/01 20:34:49 oetiker
* fixed version number and date/time

* Revision 1.1.1.1 2001/02/25 22:25:05 oetiker
