Hi Rooters,
Who can answer what is wrong?
I tried to make a simple code "test2.C" working
with TFile and TTree. It creates "test4.C" code
to read the TTree file. But after the next
commands
.L test4.C
test4 t
t.Show(1)
I got the message
"This program has performed on illegal operation
and will be shut down"
Details:
ROOT caused an invalid page fault in
module ROOT_TREE.DLL at 015f:01345c08.
What is wrong in my code? It was used on Windows 98
and this moment I have not possibility to check it
on another platform. The version of Root was 2.23.12.
In principal I would like to apply the root for saving
a 3d object, which has size ~16 GB, as a TTree. May be
it will reduce the size.
Andrei
void test2()
{
int i,j;
struct {
unsigned short s_buf[8192];
} cbuf;
TFile *ff = new TFile("ff.dat", "NEW", "Test of root file");
TTree *T = new TTree("T", "List of arrays");
TBranch *B = T->Branch("B", &cbuf, "s_buf[8192]/s");
for(i = 0; i < 10; ++i)
{
cbuf.s_buf[0] = i;
cbuf.s_buf[100] = i+10;
T->Fill();
}
T->MakeClass("test4");
ff->Close();
}
