tt_message_create(3)

NAME
     tt_message_create - create a new message object

SYNOPSIS
     #include <Tt/tt_c.h>
     Tt_message tt_message_create(void);

DESCRIPTION
     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
     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
     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.
