Method Summary

Modifier and TypeMethod and Description
public default void
callback(long
a pointer to the memory used for the function's return value.

If the function is declared as returning void, then this value is garbage and should not be used.

Otherwise, the callback must fill the object to which this points, following the same special promotion behavior as LibFFI#ffi_call. That is, in most cases, ret points to an object of exactly the size of the type specified when CIF was constructed. However, integral types narrower than the system register size are widened. In these cases your program may assume that ret points to an ffi_arg object.

public void invoke(long user_data, long obj_ptr, long type_name, int refcount)

Reports a live OpenCL API object.

Parameters
user_data:long

the user_data argument specified to ReportLiveObjectsAltera

obj_ptr:long

a pointer to the live object

type_name:long

a C string corresponding to the OpenCL API object type. For example, a leaked cl_mem object will have "cl_mem" as its type string.

refcount:int

an instantaneous reference count for the object. Consider it to be immediately stale.
