How to get user and group names from uid and gid

Hi guys,

I used to stat() to get st_uid and st_gid for an entry in a directory.
How can I get the corresponding user name/id and group name/id. I
know there are two functions like getpwuid() and getgrgid() but I
couldn't get them to work. What library is getgrgid() anyways?? Help
will be much appreciated. Thanks

getpwuid is working pretty fine in my program. Just include <pwd.h>. I work
on Solaris 2.7 & 2.8.
