tt_message_handler(3)


CDE


NAME

  tt_message_handler - retrieve the handler attribute from a message


SYNOPSIS

  #include <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 values from the
  returned pointer:

  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_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.
