Hi experts,
I've modified the tutorial macro basic.C to read an ASCII file
containing several lines of 12 elements each (3 integers and 9 reals).
Here is the macro i'm using:
{
//
// A short macro to read the Detector Map file and store the data on
some
// useful vectors
//
//
gROOT->Reset();
gBenchmark->Start("readet");
Int_t ilayer,iladder,idet;
Int_t ncols;
Int_t nlines = 0;
Float_t f1,f2,f3,f4,f5,f6,f7,f8,f9;
FILE *detfile = fopen("file.dat","r");
if (detfile <= 0) printf("Error: file could not be open\n");
printf("Reading Detector Map from file...\n");
while (1) {
ncols = fscanf(detfile,"%i %i %i %f %f %f %f %f %f %f %f
%f",
&ilayer,&iladder,&idet,&f1,&f2,&f3,&f4,&f5,&f6,&f7,&f8,&f9);
if (ncols < 0) break;
if (nlines < 5) {
printf("%i %i %i %f %f %f %f %f %f %f %f %f \n",
ilayer,iladder,idet,f1,f2,f3,f4,f5,f6,f7,f8,f9);
}
nlines++;
}
printf(" %i lines found \n",nlines);
fclose(detfile);
gBenchmark->Show("readet");
gROOT->Reset();
}
and this is what i get when i run the macro inside ROOT:
root [0] .x readet.C
Reading Detector Map from file...
Limitation: fscanf only takes upto 12 arguments
FILE:/pcct54_hdb1/barbera/galice
/v2.06pre/./readet.C LINE:34
0 lines found
readet : Real Time = 0.02 seconds Cpu Time = 0.02 seconds
root [1]
It seems that no lines are read but they indeed ARE in the file. Any
help will be greatly appreciated.
ciao
Roberto
