Description

array posix_getpwnam (string username)

- Returns an associative array containing information about a user

referenced by an alphanumeric username, passed in the

username parameter.

- The array elements returned are:

Таблица 1. The user information array
Element Description
name - The name element contains the username of the user. This is
a short, usually less than 16 character "handle" of the
user, not her real, full name. This should be the same as
the username parameter used when
calling the function, and hence redundant.
passwd - The passwd element contains the user's password in an
encrypted format. Often, for example on a system employing
"shadow" passwords, an asterisk is returned instead.
uid - User ID of the user in numeric form.
gid - The group ID of the user. Use the function
posix_getgrgid() to resolve the group
name and a list of its members.
gecos - GECOS is an obsolete term that refers to the finger
information field on a Honeywell batch processing system.
The field, however, lives on, and its contents have been
formalized by POSIX. The field contains a comma separated
list containing the user's full name, office phone, office
number, and home phone number. On most systems, only the
user's full name is available.
dir - This element contains the absolute path to the home
directory of the user.
shell - The shell element contains the absolute path to the
executable of the user's default shell.
