tt_message_context_val(3)


CDE


NAME

  tt_message_context_val - retrieve the character string of a message's
  context


SYNOPSIS

  #include <tt_c.h>
  char *tt_message_context_val(Tt_message m,
			       const char *slotname);


DESCRIPTION

  The tt_message_context_val function retrieves the character string of a
  message's context.

  The m argument is the opaque handle for the message involved in this
  operation. The slotname argument describes the context of this message.

  If there is no context slot associated with slotname,
  tt_message_context_val returns a NULL pointer.


RETURN VALUE

  Upon successful completion, the tt_message_context_val function returns the
  contents for the message argument. 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.

  TT_ERR_SLOTNAME
      The specified slotname is syntactically invalid.


APPLICATION USAGE

  The application should use tt_free(3) to free any data stored in the
  address returned by the ToolTalk API.
