Dear Rooters,
Add-on to my mail from yesterday.
http://root.cern.ch/root/roottalk/roottalk02/1293.html
I looked carefully in the ROOT digest and one
of the things that is suggested is to redirect stdout from cint.
.>[filename1] for stdout
.2>[filename2] for stderr
This works (if filename1<>filename2 apparently, otherwise there are funny
things happening).
However, if one has to use gROOT->ProcessLine() to enter the commands
(GUI case),
I found the following problem:
root [0] gROOT->ProcessLine(".>filename") //stdout redirected to
filename
Output will be saved in file filename! ('>' to display on screen)
root [1] .x Start.C // start a test script (not a GUI)
root [2] gPad // redirection okay !
root [3] gROOT->ProcessLine("gPad") // redirection failed !
(class TPad*)0x8781078
Moreover, as it has been previously written:
http://root.cern.ch/root/roottalk/roottalk00/3248.html
it seems that freopen("filename","w",stdout) doesn't redirect stdout in my
file.
Please HELP !!!
Fred
