atuser(3)						       AtFS Toolkit Library							 atuser(3)

NAME

       atUserValid, atScanUser, atUserName, atUserUid - user handling

SYNOPSIS

       #include <atfs.h>
       #include <atfstk.h>

       void atScanUser (char *userName; Af_user *resultUser);

       char* atUserName (Af_user *user);

       Uid_t atUserUid (Af_user *user);

       int atUserValid (Af_user *user);

DESCRIPTION

       atScanUser  scans  the  given string userName and tries to derive an AtFS user identification (resultUser) from it.  It does not verify the
       existence of a corresponding UNIX (/etc/passwd) user entry. Use atUserUid to test that. atScanUser understands the following formats:

       user	   When the string does not contain an at sign, it is considered to be a plain user name from the current host and domain.

       user@host   In the case that the part after the at sign doe not contain a period, it is assumed to be a hostname.  Domain  is  the  current
		   domain.

       user@host.domain
		   This  format  can  only  be	recognized, when the given domain is equal to the current domain, and the hostname remains as rest
		   between the at sign and domain name.

       user@domain
		   An user identification string with a domain name different to the local domain is treated as user@domain, although  this  might
		   be wrong.

       atUserName  returns  a string of the form user@domain generated from the given user structure. If no domain name is given in the structure,
       it returns user@host instead. With no host and no domain name, just user is returned. The result string resides in static memory  and  will
       be overwritten on subsequent calls.

       atUserUid tries to map the given user structure to a UNIX user identification. It returns the uid on success, -1 otherwise.

       atUserValid checks the given user structure for plausibility. It returns FALSE on fauilure, a non null value on success.
