# bson\_iter\_visit\_all(3)

## SYNOPSIS

```
bool
bson_iter_visit_all (bson_iter_t *iter,
                     const bson_visitor_t *visitor,
                     void *data);
```

## PARAMETERS

- •

  **iter**: A *bson\_iter\_t*.

- •

  **visitor**: A *bson\_visitor\_t*.

- •

  **data**: Optional data for **visitor**.

## DESCRIPTION

A convenience function to iterate all remaining fields of **iter** using the callback vtable provided by **visitor**.

## RETURNS

Returns true if visitation was prematurely stopped by a callback function. Returns false either because all elements were visited *or* due to corrupt BSON.

See *bson\_visitor\_t* for examples of how to set your own callbacks to provide information about the location of corrupt or unsupported BSON document entries.
