NAME

ll2_rename_user - Renames a user entry.

SYNOPSIS

#include <lastlog2.h>

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

DESCRIPTION

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);

RETURN VALUE

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.
