117 ion_user_handle_t handle;
137 * Takes an ion_allocation_data struct and returns it with the handle field
138 * populated with the opaque handle for the allocation.
146 * Takes an ion_handle_data struct and frees the handle.
153 * Takes an ion_fd_data struct with the handle field populated with a valid
154 * opaque handle. Returns the struct with the fd field set to a file
163 * Takes an ion_fd_data struct with the handle field populated with a valid
164 * opaque handle. Returns the struct with the fd field set to a file
166 * can then be passed to another process. The corresponding opaque handle can
175 * descriptor obtained from ION_IOC_SHARE and returns the struct with the handle
176 * filed set to the corresponding opaque handle.
