Valores devueltos

The array elements returned are:

**The group information array**
Element	Description
name	The name element contains the name of the group. This is a short, usually less than 16 character "handle" of the group, not the real, full name. This should be the same as the `name` parameter used when calling the function, and hence redundant.
passwd	The passwd element contains the group's password in an encrypted format. Often, for example on a system employing "shadow" passwords, an asterisk is returned instead.
gid	Group ID of the group in numeric form.
members	This consists of an array of string's for all the members in the group.

Historial de cambios

Versión	Descripción
4.2.0	Prior to this version, members was simply an integer representing the number of members in the group, and the member names were returned with numerical indices.
