-- ANSI C interface - universal (void *) pointer type
-- Author: Benedict A. Gomes <gomes@samosa.ICSI.Berkeley.EDU>


immutable class C_PTR

immutable class C_PTR is -- A pointer to void in C (void*) -- Pointer arithmetic is missing for C pointer types. Feel free to -- add it if it becomes necessary include COMPARABLE; zero:SAME is builtin C_PTR_ZERO; end; is_eq(p:SAME):BOOL is builtin C_PTR_IS_EQ; end; end;

partial class C_PTR_CONVERT

partial class C_PTR_CONVERT is -- Partial class that implements conversions to and from C_PTR -- i.e. (void *) create(vptr:C_PTR):SAME is -- create from void* -- Convert (i.e. cast) "vptr" to be of the type of SAME builtin CONVERT_FROM_C_PTR_CREATE_C_PTR; end; c_ptr:C_PTR is -- Convert (i.e. cast) this pointer to be of type C_PTR builtin CONVERT_TO_C_PTR; end; end;

immutable class C_SIZE_T

immutable class C_SIZE_T is -- Corresponds to size_t end;

immutable class C_PTRDIFF_T

immutable class C_PTRDIFF_T is -- Corresponds to ptrdiff_t end;
