#include <lastlog2.h>

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

DESCRIPTION¶

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);
