This is of course the way to do it, but your answer corresponds to the
case of a C toplevel static variable, not to the case of a C static
variable located in a function. In the first case, your variable may
be accessed by several subprograms, in the second one, it can only be
accessed by *one* C function.

This is not possible in Ada to have the equivalent of a C static
variable located in a function, you have to put it at the module
(package) level, let's say in the package body as Jon said.
