In order to access the interface, an application loads the interface library using a platform dependent system call.
Then the application locates the address of the function
nni_get_interface,
again using a platform dependent system call. Once the application has located
the central function nni_get_interface, it
requests an instance of the interface by calling the function
nni_get_interface and
specifying the desired interface version. The resulting structure contains the
interface function pointers.
After having finished using the interface functions, the application unloads the interface library using a platform dependent system call.
The sample program nnisample.c demonstrates the
interface. Also the platform dependent mechanism of loading the interface
library and the access to the function
nni_get_interface is
illustrated by this sample program.
