tt_pattern_create(library call)		       tt_pattern_create(library call)

NAME
       tt_pattern_create -- request a new pattern object

SYNOPSIS
       #include	<Tt/tt_c.h>
       Tt_pattern tt_pattern_create(void)

DESCRIPTION
       The tt_pattern_create function requests a new pattern object.

       After  receiving	 the pattern object, the application fills in the mes-
       sage pattern fields to indicate what type of messages the process wants
       to receive and then registers the pattern with the ToolTalk service.

       The  application	can supply multiple values for each attribute added to
       a pattern (although some	attributes are	set  and  can  only  have  one
       value).	 The  pattern  attribute matches a message attribute if	any of
       the values in the pattern match the value in the	message.  If no	 value
       is  specified  for  an attribute, the ToolTalk service assumes that any
       value will match.

RETURN VALUE
       Upon successful completion, the tt_pattern_create function returns  the
       opaque handle for a message pattern.  The application can use this han-
       dle in future calls to identify the pattern  object.   The  application
       can  use	tt_ptr_error(3)	to extract one of the following	Tt_status val-
       ues from	the returned handle:

       TT_OK	 The operation completed successfully.

       TT_ERR_NOMP
		 The ttsession(1) process is not running and the ToolTalk ser-
		 vice cannot restart it.

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