Hello,
I have some code that should tell me if a file is a regular file or a directory
but for any reason this does not always return a correct answer.
#include <TROOT.h>
#include <TSystem.h>
#include <sys/stat.h>
int main(int argc, char **argv)
{
void dirp = gSystem->OpenDirectory("/home/broessli/Documents/flatcone/fit");
const char afile;
struct stat st_buf;
int status;
while ((afile = gSystem->GetDirEntry(dirp)))
{
status = stat(afile,&st_buf);
if (S_ISREG (st_buf.st_mode)) {
printf ("%s is a regular file.\n", afile);
}
if (S_ISDIR (st_buf.st_mode))
{
printf ("%s is a directory.\n", afile);
}
}
gSystem->FreeDirectory(dirp);
return 0;
}
e.g. on my directory
vv is a directory. OK
fgui.C~ is a directory. NO
basic2.C is a directory. NO
str.cc is a directory. NO
t~ is a directory. NO
…
while running the code independently from Root works:
#include <stdio.h>
#include <errno.h>
#include <sys/stat.h>
int main (int argc, char *argv[]) {
int status;
struct stat st_buf;
if (argc != 2) {
printf ("Usage: progName <fileSpec>\n");
printf (" where <fileSpec> is the file to check.\n");
return 1;
}
status = stat (argv[1], &st_buf);
if (status != 0) {
printf ("Error, errno = %d\n", errno);
return 1;
}
if (S_ISREG (st_buf.st_mode)) {
printf ("%s is a regular file.\n", argv[1]);
}
if (S_ISDIR (st_buf.st_mode)) {
printf ("%s is a directory.\n", argv[1]);
}
return 0;
}
e.g.
/home/broessli/Documents/flatcone/fit/t~ is a regular file.
Thank You in advance for help,
Bertrand Roessli
PS: I have Root5.18
