Dear root users,
I want to use TROOT::ProcessLine() to execute multiple scripts
with some conditions from a single top script. The user guide v3.05
simply mentions the name of this method and says it can be used for this
purpose. It also mentions an example from
$ROOTSYS/tutorials/cernstaff.C. I went through the cernstaff.C file, but
it only demonstrates how to create and fill a tree, set branches,etc,
including nothing on how to use TROOT::ProcessLine().
I seached in "root.cern.ch", finding only this:
"ProcessLine(const char* line, Int_t* error = 0)"
and
"void ProcessLine(const char *line, Int_t *error)
Process interpreter command via TApplication::ProcessLine().
On Win32 the line will be processed a-synchronously by sending
it to the CINT interpreter thread. For explicit synchrounous processing
use ProcessLineSync(). On non-Win32 platforms there is not difference
between ProcessLine() and ProcessLineSync().
The possible error codes are defined by TInterpreter::EErrorCode. In
particular, error will equal to TInterpreter::kProcessing until the
CINT interpreted thread has finished executing the line."
The second long explantion includes no examples on how to use
ProcessLine().
Then I tried to do the following on the root prompt:
root[] .L myfile.C
root[] gROOT.ProcessLine("myfile.C")
but root says "..Symbol myfile is not defined in current scope ...". So
I have no idea on how to use it. Can anyone kindly help me?
The version of ROOT I am using is 3.05/04.
Thanks in advance!
