Bug ID: 78080
Summary: chown command (sys/stat.h) fail to change the owner
directory if the return value is not attributed to a
variable.
Product: gcc
Version: 5.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: rosemberg at ymail dot com
Target Milestone: ---
Hi,
chown command (sys/stat.h) fail to change the owner directory if the return
value is not attributed to a variable.
Supposed the directory /home/user/tochange exists and the program is running
with administrator rights and tochange owner and group is not the same like its
parent directory .
example of success code:
#include <string>
#include <iostream>
#include <sys/stat.h>
int main()
{
string sPath("/home/user/tochange");
struct stat info;
stat("/home/user",&info);
int iA = chown(sPath.c_str(), info.st_uid, info.st_gid);
cout << iA << endl;
return 0;
}
The result to iA will be 0 (success)
If I change the last 2 lines (before return 0;) to the follow code, the chown
command failed and cout will return -1 (nothing was changed):
cout << chown(sPath.c_str(), info.st_uid, info.st_gid) << endl;
it also happened with if statement.
Best regards,
M.Rosemberg
