bool
bson_append_vector_packed_bit_uninit (bson_t *bson,
                                      const char *key,
                                      int key_length,
                                      size_t element_count,
                                      bson_vector_packed_bit_view_t *view_out);

Parameters#

  • bson: A bson_t.

  • key: An ASCII C string containing the name of the field.

  • key_length: The length of key in bytes, or -1 to determine the length with strlen().

  • element_count: Number of elements to allocate space for.

  • view_out: Receives a bson_vector_packed_bit_view_t with uninitialized elements.

Description#

Appends a new field to bson by allocating a Vector with the indicated number of packed_bit elements. The elements will be uninitialized. On success, the caller must write every element in the Vector if the resulting bson_t is to be used.

The view written to *view_out is only valid until bson is otherwise modified or freed.

Returns#

Returns true if the operation was applied successfully. The function fails if appending the array grows bson larger than INT32_MAX.
