134 * Takes an ion_allocation_data struct and returns it with the handle field
135 * populated with the opaque handle for the allocation.
143 * Takes an ion_handle_data struct and frees the handle.
150 * Takes an ion_fd_data struct with the handle field populated with a valid
151 * opaque handle. Returns the struct with the fd field set to a file
160 * Takes an ion_fd_data struct with the handle field populated with a valid
161 * opaque handle. Returns the struct with the fd field set to a file
163 * can then be passed to another process. The corresponding opaque handle can

173 * filed set to the corresponding opaque handle.
