Can you tell me how to get the User name and Group
name of a file in the UNIX? I can only get the User ID
and Group ID by calling 'stat' or 'lstat'.
Thank yo

What Unix system you use?
In Solaris:
ls -l

struct passwd * uptr = getpwuid(uid_t uid);
struct group * gptr = getgrgid(gid_t gid);
printf("%s", uptr->pw_name );
printf("%s", gptr->gr_name);

Yes. Now I can use function getpwuid() to get the
owner of file, but how to get the group name?
