LL2_RENAME_USER(3) Programmers Manual LL2_RENAME_USER(3)
ll2_rename_user - Renames a user entry.
#include <lastlog2.h>
int ll2_rename_user (struct ll2_context *context, const char
*user, const char *newname, char **error);
Changes 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);
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.
