   9  * prevent small leak when resources are exhausted -- Mike Slifcak
  10  *
  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.

  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.
