            char *symbol;
        } v_symbol;
    } value;
} bson_value_t;

DESCRIPTION

The bson_value_t structure is a boxed type for encapsulating a runtime determined type.

EXAMPLE

const bson_value_t *value;
value = bson_iter_value(&iter);
if (value.type == BSON_TYPE_INT32) {
    printf("%d
", value.value.v_int32);
}
