tttk_message_create(3) ToolTalk Functions tttk_message_create(3)NAMEtttk_message_create - create a message conforming to the CDE conven‐
tions
SYNOPSIS
#include <Tt/tttk.h>
Tt_message tttk_message_create(Tt_message context,
Tt_class the_class,
Tt_scope the_scope,
const char *handler,
const char *op,
Tt_message_callback callback);
DESCRIPTION
The tttk_message_create() function creates a message that propagates
inherited contexts from one message to another. The tttk_message_cre‐
ate() function creates a message and copies onto it all the context
slots from context whose slotname begins with the characters ENV_. It
gives the created message a Tt_class of the_class and a Tt_scope of
the_scope. If handler is not NULL, then tttk_message_create()
addresses the message as a TT_HANDLER to that procid; otherwise, it
gives the message a Tt_address of TT_PROCEDURE. It sets the message's
op to op if op is not NULL. If callback is not NULL, tttk_message_cre‐
ate() adds it to the message as a message callback.
RETURN VALUE
Upon successful completion, the tttk_message_create() function returns
the created Tt_message , which can be modified, sent, and destroyed
like any other Tt_message ; 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_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
service cannot restart it.
TT_ERR_PROCID
The specified process identifier is out of date or invalid.
