tt_pattern_create(3)
CDE
NAME
  tt_pattern_create - request a new pattern object

SYNOPSIS
  #include <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 message
  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 handle in
  future calls to identify the pattern object. The application can use
  tt_ptr_error(3) to extract one of the following Tt_status values from the
  returned handle:

  TT_OK
      The operation completed successfully.

  TT_ERR_NOMP
      The ttsession(1) process is not running and the ToolTalk service 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.
