8 * Revision 1.5 2003/02/13 07:05:27 oetiker
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.
18 *
19 * -- Peter Stamfest <peter@stamfest.at>
20 *
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.
