Ubuntu文件所有权cpp

Question

As in description. I need to find out who own a file using cpp code, i am using boost filesystem, codeblocks on ubuntu 12.04 (which is irrelevant, but). If anyone could give me function name, or reference link, to particular function, i would be greatful.

Answer 1

boost::filesystem does not support this functionality, you can obtain file attributes, but that's it.

Something like this should work:

#include <sys/stat.h>

struct stat st;
stat("myFile.txt", &st);
struct passwd *pw = getpwuid(st.st_uid);
struct group  *gr = getgrgid(st.st_gid);

Note: The previous code is not error safe, that's up to you
