ttdt_subcontract_manage(library call) ttdt_subcontract_manage(library call) NAME ttdt_subcontract_manage -- manage an outstanding request SYNOPSIS #include <Tt/tttk.h> Tt_pattern *ttdt_subcontract_manage( Tt_message subcontract, Ttdt_contract_cb cb, Widget shell, void *clientdata); DESCRIPTION The ttdt_subcontract_manage function allows a requester to manage the standard Desktop interactions with the tool that is handling the re- quest. The ttdt_subcontract_manage function registers in the default session for TT_HANDLER-addressed requests Get_Geometry and Get_XInfo, and Status notices. If shell is not NULL, the ToolTalk service handles the Get_Geometry and Get_XInfo notices transparently; otherwise, it passes them to cb. The Status notice is always passed to the callback. See ttdt_session_join(3) for a description of a Ttdt_contract_cb call- back. If subcontract is destroyed by tttk_message_destroy, then the patterns will also be destroyed; otherwise, the caller is responsible for iter- ating over the array and destroying each pattern. RETURN VALUE Upon successful completion, the ttdt_subcontract_manage function re- turns a null-terminated array of Tt_pattern, and associates this array with subcontract; otherwise, it returns an error pointer. The applica- tion can use tt_ptr_error(3) to extract one of the following Tt_status values from the returned handle: TT_DESKTOP_EINVAL Both the shell and cb arguments were NULL. TT_ERR_NOMEM There is insufficient memory available to perform the func- tion. TT_ERR_NOMP The ttsession(1) process is not running and the ToolTalk ser- vice cannot restart it. TT_ERR_POINTER The subcontract argument was not a valid Tt_message. TT_ERR_PROCID The specified process identifier is out of date or invalid.
