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:

    The operation completed successfully.
    The ttsession(1) process is not running and the ToolTalk service cannot restart it.
    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.
