   9  * Find attached the patch I promised to send to you. Please note that there
  10  * are three new source files (src/rrd_is_thread_safe.h, src/rrd_thread_safe.c
  11  * and src/rrd_not_thread_safe.c) and the introduction of librrd_th. This
  12  * library is identical to librrd, but it contains support code for per-thread
  13  * global variables currently used for error information only. This is similar
  14  * to how errno per-thread variables are implemented.  librrd_th must be linked
  15  * alongside of libpthred
  16  *
  17  * There is also a new file "THREADS", holding some documentation.

  21  * Revision 1.4  2002/02/01 20:34:49  oetiker
  22  * fixed version number and date/time
  23  *
  24  * Revision 1.3  2001/03/10 23:54:39  oetiker
  25  * Support for COMPUTE data sources (CDEF data sources). Removes the RPN
  26  * parser and calculator from rrd_graph and puts then in a new file,
  27  * rrd_rpncalc.c. Changes to core files rrd_create and rrd_update. Some
  28  * clean-up of aberrant behavior stuff, including a bug fix.
  29  * Documentation update (rrdcreate.pod, rrdupdate.pod). Change xml format.
