CDE


NAME

  tt_spec_prop - retrieve the ith value of the property associated with an
  object spec


SYNOPSIS

  #include <tt_c.h>
  char *tt_spec_prop(const char *objid,
		     const char *propname,
		     int i);


DESCRIPTION

  The tt_spec_prop function retrieves the ith value of the property
  associated with this object spec.

  The objid argument is the identifier of the object involved in this
  operation. The propname argument is the name of the property associated
  with the object spec. The i argument is the item of the list whose value is
  to be retrieved.  The list numbering begins with zero.


RETURN VALUE

  Upon successful completion, the tt_spec_prop function returns the contents
  of the property value. If there are i values or less, tt_spec_prop returns
  NULL.	 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_DBAVAIL
      The ToolTalk service could not access the ToolTalk database needed for
      this operation.

  TT_ERR_DBEXIST
      The ToolTalk service could not access the specified ToolTalk database
      in the expected place.

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

  TT_ERR_NUM
      The integer value passed was invalid (out of range).

  TT_ERR_OBJID
      The objid passed to the ToolTalk service does not reference an existing
      object spec.

  TT_ERR_PROPNAME
      The specified property name 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.

  If the returned value has embedded nulls, its length cannot be determined.
