NAME

       bson_append_array_begin - bson_append_array_begin()

SYNOPSIS

          #define BSON_APPEND_ARRAY_BEGIN(b, key, child) \
             bson_append_array_begin (b, key, (int) strlen (key), child)

          bool
          bson_append_array_begin (bson_t *bson,
                                   const char *key,
                                   int key_length,
                                   bson_t *child);

PARAMETERS

       • bson: A bson_t.

       • key: A string containing the name for the key.

       • key_length: The length of key or -1 to call strlen().

       • child: A bson_t.

DESCRIPTION

       The  bson_append_array_begin() function shall begin appending an array field to bson. This
       allows for incrementally building a  sub-array.  Doing  so  will  generally  yield  better
       performance  as  you  will serialize to a single buffer. When done building the sub-array,
       the caller MUST call bson_append_array_end().

       For generating array element keys, see bson_uint32_to_string.

RETURNS

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