/**
* @brief Get the mapping between the input vertex in the space space 0 .. stinger_vertices_max_vertices_get()-1 and its representative
* string if it exists.
*
* This function assumes that the input buffer might could already be allocated, but will allocate / reallocate as needed.
*
* @param S Pointer to the stinger graph.
* @param vertexID The vertex from which to get the string.
* @param outbuffer Output buffer where you would like the data to be placed.
* @param outbufferlength The length of the output buffer (will be set or increased if allocated / reallocated or if string is shorter).
* @retrun 0 on success, -1 on failure.
