NAME [Toc] [Back]
tt_message_create - create a new message object
SYNOPSIS [Toc] [Back]
#include <Tt/tt_c.h>
Tt_message tt_message_create(void)
DESCRIPTION [Toc] [Back]
The tt_message_create function creates a new message object.
The ToolTalk service returns a message handle that is an opaque
pointer to a ToolTalk structure.
RETURN VALUE [Toc] [Back]
Upon successful completion, the tt_message_create function returns the
unique opaque handle that identifies the message object. 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 process identification is not valid.
APPLICATION USAGE [Toc] [Back]
A return value of TT_ERR_PROCID implies that tt_open(3) was not issued
before tt_message_create.
If the ToolTalk service is unable to create a message when requested,
tt_message_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.
