19 · bson: A bson_t.
20
21 · key: A string containing the name for the key.
22
23 · key_length: The length of key or -1 to call strlen().
24
25 · child: A bson_t.

28 The bson_append_array_begin() function shall begin appending an array
29 field to bson. This allows for incrementally building a sub-array.
30 Doing so will generally yield better performance as you will serialize
31 to a single buffer. When done building the sub-array, the caller MUST
32 call bson_append_array_end().
33
34 For generating array element keys, see bson_uint32_to_string.
35
37 Returns true if the operation was applied successfully. The function
38 will fail if appending the array grows bson larger than INT32_MAX.
