Today you sent me mail regarding [rrd-users] Some newbie questions...:
*> Hi everybody!
*> I found this great tool some days ago and start to observe variables
*> of my system (eth* in and out,average load,mem,etc.).
*> Because everything works fine, I start to walk through the
*> directories of RRDTool. I've found in the lib-directory a file
*> called librrd.a ... Hmmm... It seems to be a library with some
*> calls to the rrd-functions inside. So the first question is:
*> Does anybody have a documentation about this library?
there is no explicit documentation but the interface to the main
function blocks uses argv equivalent to stand alone utils ... check
the rrd_tool.c for a sample implementation.
*> When I run make I got a loooot of warnings like:
*> cgi.c:214: warning: pointer of type `void *' used in arithmetic
*> gd.c:319: warning: declaration of `y1' shadows global declaration
*> gd.c: In function `gdImageDashedLine':
*> Should I ignore these warnings? Because I'm not sure, I currently
*> use rrdtool 1.0.17 (which produces no warnings).
the difference is that 1.0.25 has some more warnings enabled ...
the code of 25 is actually cleaner than the code of 17 ... patches
to cleane it up further are welcome ...
*> So long...Andreas.
