Syntax

#include <sys/types.h>
#include <auth.h>

Description

The getauthuid function looks up the auth entry for the specified user ID and returns a pointer to a static area containing it.

The storeauthent function will store the specified auth entry into the local auth database, overwriting any existing entry with the same a_uid field. 

The setauthfile function will set the pathname of the file to be used for the local auth database in all subsequent operations.

The endauthent functions closes the auth database.  Subsequent calls to getauthuid and storeauthent will reopen it.

The auth database may be distributed via the BIND/Hesiod naming service. 

Restrictions

Only the super-user and members of the group authread may read information from the auth database. 

Only the super-user may modify the auth database. 

The auth databse may not be distributed via the Yellow Pages service. 

Return Value

Functions which return a pointer value will return the null pointer (0) on EOF or error.  Other functions will return zero (0) on success and a negative value on failure. 

Files

/etc/auth.[pag,dir]
