BSON_ITER_OVERWRITE_BINARY(3)

SYNOPSIS

    void
    bson_iter_overwrite_binary (bson_iter_t *iter,
                                bson_subtype_t subtype,
                                uint32_t *binary_len,
                                uint8_t **binary);

PARAMETERS

•   iter: A bson_iter_t.

•   subtype: The expected bson_subtype_t.

•   binary_len: A location for the length of binary.

•   binary: A location for a pointer to the mutable buffer.

DESCRIPTION

The bson_iter_overwrite_binary() function obtains mutable access to a BSON_TYPE_BINARY element in place.

This may only be done when the underlying bson document allows mutation.

It is a programming error to call this function when iter is not observing an element of type BSON_TYPE_BINARY and the provided subtype.

The buffer that binary points to is only valid until the iterator's bson_t is otherwise modified or freed.
