SYNOPSIS
#include <Tt/tt_c.h>
char *tt_message_handler(
Tt_message m);
DESCRIPTION
The tt_message_handler function retrieves the handler attribute from
the specified message.
The m argument is the opaque handle for the message involved in this
operation.
RETURN VALUE
Upon successful completion, the tt_message_handler function returns the
character value that uniquely identifies the process that is to handle
the message (Tt_state = TT_CREATED or TT_SENT) or the process that did
handle the message (Tt_state = TT_SENT or TT_HANDLED). The application
can use tt_ptr_error(3) to extract one of the following Tt_status val‐
ues from the returned pointer:
TT_OK The operation completed successfully.
TT_ERR_NOMP
The ttsession(1) process is not running and the ToolTalk ser‐
vice cannot restart it.
TT_ERR_POINTER
The pointer passed does not point to an object of the correct
type for this operation.
APPLICATION USAGE
The application should use tt_free(3) to free any data stored in the
address returned by the ToolTalk API.
