2013-07-19change uid_t, gid_t, and id_t to unsigned typesRich Felker2-6/+20
this change is both to fix one of the remaining type (and thus C++ ABI) mismatches with glibc/LSB and to allow use of the full range of uid and gid values, if so desired. passwd/group access functions were not prepared to deal with unsigned values, so they too have been fixed with this commit.
2013-04-04add put*ent functions for passwd/group files and similar for shadowRich Felker3-0/+34
since shadow does not yet support enumeration (getspent), the corresponding FILE-based get and put versions are also subbed out for now. this is partly out of laziness and partly because it's not clear how they should work in the presence of TCB shadow files. the stubs should make it possible to compile some software that expects them to exist, but such software still may not work properly.
2013-02-17add fgetgrent functionRich Felker1-0/+9
based on patch by Isaac Dunham, moved to its own file to avoid increasing bss on static linked programs not using this nonstandard function but using the standard getgrent function, and vice versa.
