vertex_format_delete(formatID);
Returns: N/A
This function must be called whenever you are finished using any
created vector formats. You provide the format ID value (as
returned by the function vector_format_end()), and
this function will free the memory associated with it. Note that if
you try to use this format again after calling this function, you
will get an error.
vertex_format_delete(myFormat);
The above code will remove the vertex format created in the variable "myFormat" from memory.
