Hi Erik, Hi to all, This is part five of the my_get*id story. I've tweaked a bit this two functions to make them more flexible, but this changes will not affect existing code. Now they work so: 1) my_getpwuid( char *user, uid_t uid, int bufsize) if bufsize is > 0 char *user cannot be set to NULL on success username is written on static allocated buffer on failure uid as string is written to buffer and NULL is returned if bufsize is = 0 char *user can be set to NULL on success username is returned on failure NULL is returned if bufsize is < 0 char *user can be set to NULL on success username is returned on failure an error message is printed and the program exits 2) 1) my_getgrgid( char *group, uid_t uid, int bufsize) if bufsize is > 0 char *group cannot be set to NULL on success groupname is written on static allocated buffer on failure gid as string is written to buffer and NULL is returned if bufsize is = 0 char *group can be set to NULL on success groupname is returned on failure NULL is returned if bufsize is < 0 char *group can be set to nULL on success groupname is returned on failure an error message is printed and the program exits This changes were needed mainly for my new id applet. It is somewhat bigger then the previous but matches the behaviour of GNU id and is capable to handle usernames of whatever length. BTW: at a first look it seems to me that it will integrate well (with just a few changes) with the pending patch in patches/id_groups_alias.patch. The increase in size is balanced by the removal of my_getpwnamegid.c from libbb as this was used only in previous id applet and by size optimizations made possible in whoami.c and in passwd.c. I know that we are in feature freeze but I think that i've tested it enough (at least I hope so.......).
