- Written by Alain Magloire.
- Simple replacement for fgetpwent(), it is not :
- - thread safe;
- - static buffer was not use since it will limit the size
- of the entry. But rather memory is allocated and __never__
- release. The memory will grow if need be.
- - no support for shadow
- - no support for NIS(+)
