Hello, I am trying to extract the modification time of a text file, pico.txt, under root Cint. When I use the method GetPathInfo of TSystem, the parameters values of the method seem to be not stored, even if the file is recognized (GetPathInfo is set to 0). When putting the trace mode on, the problem seems to come from the file declaration. ******************************************* * * * W E L C O M E to R O O T * * * * Version 3.03/09 2 June 2003 * * * * You are welcome to visit our Web site * * http://root.cern.ch * * * ******************************************* Compiled for linux with thread support.

Enclose multiple statements between { }. root [0] Long_t *id,*size,*flags,*mt; root [1] gSystem->GetPathInfo("/pathname/pico.txt",id,size,flags,mt) (int)0 root [2] id (Long_t*)0x0 root [3] size (Long_t*)0x0 root [4] flags (Long_t*)0x0 root [5] mt (Long_t*)0x0 root [6] .T Trace mode on 1 root [7] mt {mt; 2 } # _iostream 63 G__ateval(long* const & x) {return(0);} (Long_t*)0x0 I get the same problem if I write a macro using /sys/stat librarie and trying to assign the buffer value myself: #include <sys/types.h> #include <sys/stat.h> #include <stdio.h> #include "Riostream.h" #include <stdlib.h> void analy() { struct stat buf; ifstream in; in.open("pico.txt", ios::in); stat(in, &buf); printf ("proprietaire %d, taille %d\n", buf.st_uid, buf.st_size); } Am I doing something wrong? Thanks a lot in advance, Eric
