I wonder if I'm hosing things up because I'm calling mysql_init without an
argument. The API says that if the argument is null, it returns back a fresh
mysql handle.  That's what I was intending.  But, by not explicitly handing
in NULL, i may be corrupting matters.

How do I rewrite:
  (define c-mysql-init (get-ffi-obj  "mysql_init" libmysql (_fun ->
so that the function takes in an explicit NULL?


Have an idea for software?  I can make it happen -
