Functions | |
| VX_API_ENTRY vx_user_data_object VX_API_CALL | vxCreateUserDataObject (vx_context context, const vx_char *type_name, vx_size size, const void *ptr) |
| Creates a reference to a User Data Object. | |
| VX_API_ENTRY vx_user_data_object VX_API_CALL | vxCreateVirtualUserDataObject (vx_graph graph, const vx_char *type_name, vx_size size) |
| Creates an opaque reference to a virtual User Data Object with no direct user access. | |
| VX_API_ENTRY vx_status VX_API_CALL | vxReleaseUserDataObject (vx_user_data_object *user_data_object) |
| Releases a reference of a User data object. The object may not be garbage collected until its total reference count is zero. After returning from this function the reference is zeroed. | |
| VX_API_ENTRY vx_status VX_API_CALL | vxQueryUserDataObject (vx_user_data_object user_data_object, vx_enum attribute, void *ptr, vx_size size) |
| Queries the User data object for some specific information. | |
| VX_API_ENTRY vx_status VX_API_CALL | vxCopyUserDataObject (vx_user_data_object user_data_object, vx_size offset, vx_size size, void *user_ptr, vx_enum usage, vx_enum user_mem_type) |
| Allows the application to copy a subset from/into a user data object. | |
| VX_API_ENTRY vx_status VX_API_CALL | vxMapUserDataObject (vx_user_data_object user_data_object, vx_size offset, vx_size size, vx_map_id *map_id, void **ptr, vx_enum usage, vx_enum mem_type, vx_uint32 flags) |
| Allows the application to get direct access to a subset of the user data object. | |
| VX_API_ENTRY vx_status VX_API_CALL | vxUnmapUserDataObject (vx_user_data_object user_data_object, vx_map_id map_id) |
| Unmap and commit potential changes to a user data object subset that was previously mapped. Unmapping a user data object subset invalidates the memory location from which the subset could be accessed by the application. Accessing this memory location after the unmap function completes is implementation specific. | |
