user names

[zskater]

my problem is I cant find how to access the users name who created each file in a directory
I know using ls -l can tell you this but Im not accessing it from the command line

For finding the size of the files and the times they were last modified I have been using stbuf.st_size and stbuf.st_mtime
both from stat.h

In stat.h there is information for getting UID and GID but I cant find anything for the actual name (user name eg. steve)

Can anyone help

Cheers Steve

If i remember correct there is a fuction "id" which gives the current Id.

Be easy.
Just call "ls -l" trough system(); call
and parse the output.
Will work on all unixes.

How about this?

Use stat to get the UID for the file and then call getpwent to convert UID into a name:

#include <sys/types.h>
#include <sys/stat.h>
#include <pwd.h>

struct passwd *userinfo;
struct stat buf;
char *filespec = &quot;/usr/home/example&quot;;

stat(filespec, &buf);
userinfo = getpwuid(buf.st_uid);
printf(&quot;User %s owns file %s\n&quot;, userinfo.pw_name, filespec);
