Description

to_global Returns a pointer that points to a region in the global address space if to_global can cast ptr to the global address space. Otherwise it returns NULL.

to_local Returns a pointer that points to a region in the local address space if to_local can cast ptr to the local address space. Otherwise it returns NULL.

to_private Returns a pointer that points to a region in the private address space if to_private can cast ptr to the private address space. Otherwise it returns NULL.

get_fence returns a valid memory fence value for ptr.

The generic type gentype is used to indicate any of the built-in data types supported by OpenCL C or a user defined type.
