SYNOPSIS
#include <Tt/tt_c.h>
Tt_message tt_pnotice_create(Tt_scope scope,
const char *op);
DESCRIPTION
The tt_pnotice_create() function creates a message. The created mes‐
sage contains the following:
Tt_address = TT_PROCEDURE
Tt_class = TT_NOTICE
The application can use the returned handle to add arguments and other
attributes, and to send the message.
The scope argument determines which processes are eligible to receive
the message. The following values are defined:
TT_SESSION
All processes joined to the indicated session are eligible.
TT_FILE
All processes joined to the indicated file are eligible.
TT_BOTH
All processes joined to either indicated file or the indi‐
cated session are eligible.
TT_FILE_IN_SESSION
All processes joined to both the indicated file and the
indicated session are eligible.
The op argument is the operation to be performed by the receiving
process.
RETURN VALUE
Upon successful completion, the tt_pnotice_create() function returns
the unique handle that identifies this message. The application can
use tt_ptr_error(3) to extract one of the following Tt_status values
from the returned handle:
TT_OK The operation completed successfully.
TT_ERR_NOMP
The ttsession(1) process is not running and the ToolTalk
service cannot restart it.
TT_ERR_PROCID
The specified process identifier is out of date or invalid.
APPLICATION USAGE
The application should use tt_free(3) to free any data stored in the
address returned by the ToolTalk API.
If the ToolTalk service is unable to create a message when requested,
tt_pnotice_create() returns an invalid handle. When the application
attempts to use this handle with another ToolTalk function, the
ToolTalk service will return TT_ERR_POINTER.
