* add put*ent functions for passwd/group files and similar for shadowRich Felker2013-04-043-0/+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.
* add fgetgrent functionRich Felker2013-02-171-0/+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.
