Description

The define-c-typedef macro is used to define FLI type specifiers, which corresponds to those defined using the C function typedef. It is a convenience function, as types can also be defined using define-foreign-type.

Example

In the following example three types are defined using the FLI function define-c-typedef, and the corresponding C definitions are then given.

(fli:define-c-typedef intptr (:pointer :int))

(fli:define-c-typedef bar (:struct (one :int)))

These are the corresponding C typedef definitions:

typedef int *intptr;

typedef struct (int one;) bar;
