The + _NET_MAX_SELECTION_SIZE target should be always the first target in the + MULTIPLE request. + + The target _NET_MAX_SELECTION_SIZE is a side-effect target, as described + in ICCCM section 2.6.3. When handling this target, the matching property on + the requestor window should be of type XA_INTEGER, format 32, with 2 + elements. + + If the selection owner's connection to the X server is local, the first + element is used as the limit, otherwise the second element is used as the + limit. A local connection is identified by a value of XDisplayString() with + the first character ':', for example, ":0.0". A value of -1 for either + element means no limit. + + The value should limit the sum of the sizes in the request, not separately + each of them. The client should reject subsequent targets if they would + cause the total amount of data transferred for all targets to exceed the + limit. Note that there is no requirement that if one target is rejected, + all other targets will be rejected or all that subsequent targets will be + rejected. + + Clients are not required to limit the data size precisely to the given + value. If the computation of the data size would be expensive for the + client, a certain reasonable inaccurancy is allowed. In other words, if the + client for various reasons doesn't know exact size of the data to be + transfered, it should try to estimate it, rather than transfering data with + size that is possibly magnitudes larger. + + The intent of this target is to avoid unwanted large transfers, so it + should be requsted only by xclipboard-like tools. They should use a request + of type MULTIPLE with _NET_MAX_SELECTION_SIZE as the first target in the + MULTIPLE request, with the requested target(s) after it. |
