9  * prevent small leak when resources are exhausted -- Mike Slifcak

11  * Revision 1.6  2004/05/25 20:51:49  oetiker
12  * Update displayed copyright messages to be consistent. -- Mike Slifcak
13  *
14  * Revision 1.5  2003/02/13 07:05:27  oetiker
15  * Find attached the patch I promised to send to you. Please note that there
16  * are three new source files (src/rrd_is_thread_safe.h, src/rrd_thread_safe.c
17  * and src/rrd_not_thread_safe.c) and the introduction of librrd_th. This
18  * library is identical to librrd, but it contains support code for per-thread
19  * global variables currently used for error information only. This is similar
20  * to how errno per-thread variables are implemented.  librrd_th must be linked
21  * alongside of libpthred
22  *
23  * There is also a new file "THREADS", holding some documentation.
24  *
25  * -- Peter Stamfest <peter@stamfest.at>
26  *
27  * Revision 1.4  2002/02/01 20:34:49  oetiker
28  * fixed version number and date/time
29  *
30  * Revision 1.3  2001/03/10 23:54:39  oetiker
31  * Support for COMPUTE data sources (CDEF data sources). Removes the RPN
32  * parser and calculator from rrd_graph and puts then in a new file,
33  * rrd_rpncalc.c. Changes to core files rrd_create and rrd_update. Some
34  * clean-up of aberrant behavior stuff, including a bug fix.
35  * Documentation update (rrdcreate.pod, rrdupdate.pod). Change xml format.
