NAMEttdt_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
request. 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
returns a null-terminated array of Tt_pattern, and associates this
array with subcontract; otherwise, it returns an error pointer. The
application 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The specified process identifier is out of date or invalid.
