bson_destroy_with_steal()

Synopsis

uint8_t *
bson_destroy_with_steal (bson_t   *bson,
                         bool      steal,
                         uint32_t *length);

Parameters

bson	A bson_t.
steal	A bool indicating if the underlying buffer should be stolen.
length	A location for storing the resulting buffer length.

Description

The bson_destroy_with_steal() function shall destroy a bson_t structure but return the underlying buffer instead of freeing it. If steal is false, this is equivalent to calling bson_destroy(). It is a programming error to call this function on a bson_t that is not a top-level bson_t, such as those initialized with bson_append_document_begin(), bson_append_array_begin(), and bson_writer_begin().

See also bson_steal, a higher-level function that efficiently transfers the contents of one bson_t to another.

Returns

bson_destroy_with_steal() shall return a buffer containing the contents of the bson_t if steal is non-zero. This should be freed with bson_free() when no longer in use. length will be set to the length of the bson document if non-NULL.
