posix_getgrgid — Return info about a group by group id
Gets information about a group provided its id.
The group id.
The array elements returned are:
|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.|
|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.|
