NAME         top

       ll2_rename_user - Renames an user entry.

SYNOPSIS         top

       #include <lastlog2.h>

       int ll2_rename_user (struct ll2_context *context, const char
       *user, const char *newname, char **error);

DESCRIPTION         top

       Changing user name from user to newname of one entry in database,
       which is defined by context. All other entries with the user user
       will be deleted. If context is NULL, the default database,
       defined in LL2_DEFAULT_DATABASE, will be taken.

           char    *error = NULL;
           const   char *user = "root";
           const   char *new_user = "notroot";

           int ret = ll2_rename_user (NULL, user, new_user, &error);

RETURN VALUE         top

       Returns 0 on success, -ENOMEM or -1 on other failure. error
       contains an error string if the return value is -1. error is not
       guaranteed to contain an error string, could also be NULL. error
       should be freed by the caller.
