Возвращаемые значения
The array elements returned are:
| 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. |
| 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, should be the same as the gid parameter used when calling the function, and hence redundant. |
| members | This consists of an array of string's for all the members in the group. |
Список изменений
| Версия | Описание |
|---|---|
| 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. |
