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.
