snapshot_target(3) Arcan Lua API snapshot_target(3) NAME snapshot_target - Request that a frameserver serializes its internal state into the specified resource. SYNOPSIS bool:status snapshot_target( vid:target, string:resource ) snapshot_target( .B ) snapshot_target( vid:target, string:resource, number:namespace, string:de- scription ) DESCRIPTION Create a new resource in the APPL_STATE_RESOURCE namespace and send a file reference there to target requesting that it stores its state from the resource. This returns false if the file could not be created due to permissions, and true if the file was created and sent successfully. If namespace is provided and the namespace is writable, the resource will in- stead be created within that namespace. Depending if the type of the seg- ment is a CLIPBOARD or a normal application window with a bchunk state ex- posed or in a mouse-drag, the client will interpret the operation as a save, paste or drag-and-drop. If a description is provided, a short (~60ch) text type descriptor of the data can be amended. The convention is to treat this as a simplified MIME - type, with the application/ prefix be- ing the default (and can thus be omitted). NOTES 1 Normally only the APPL_TEMP_RESOURCE is writable, but the mechanism is reserved for user- defined namespaces as well. targetcontrol August 2026 snapshot_target(3)
