NAME

       bson_iter_binary - bson_iter_binary()

SYNOPSIS

          #define BSON_ITER_HOLDS_BINARY(iter) \
             (bson_iter_type ((iter)) == BSON_TYPE_BINARY)

          void
          bson_iter_binary (const bson_iter_t *iter,
                            bson_subtype_t *subtype,
                            uint32_t *binary_len,
                            const uint8_t **binary);

PARAMETERS

       • iter: A bson_iter_t.

       • subtype: A location for a bson_subtype_t or NULL.

       • binary_len: A location for the length of binary.

       • binary: A location for a pointer to the immutable buffer.

DESCRIPTION

       This  function  shall  return  the  binary  data  of  a  BSON_TYPE_BINARY element. It is a
       programming error to call this function on a field that is not of  type  BSON_TYPE_BINARY.
       You can check this with the BSON_ITER_HOLDS_BINARY() macro or bson_iter_type().

       The  buffer that binary points to is only valid until the iterator's bson_t is modified or
       freed.
