# com_print_typeinfo

(PHP 4 >= 4.2.0, PHP 5, PHP 7)

com_print_typeinfo — Print out a PHP class definition for a dispatchable interface

### 说明

com_print_typeinfo ( object `$comobject` [, string `$dispinterface` [, bool `$wantsink` = `FALSE` ]] ) : bool

The purpose of this function is to help generate a skeleton class for use as an event sink. You may also use it to generate a dump of any COM object, provided that it supports enough of the introspection interfaces, and that you know the name of the interface you want to display.

### 参数

`comobject`

  `comobject` should be either an instance of a COM object, or be the name of a typelibrary (which will be resolved according to the rules set out in com_load_typelib()).

`dispinterface`

  The name of an IDispatch descendant interface that you want to display.

`wantsink`

  If set to `TRUE`, the corresponding sink interface will be displayed instead.

### 返回值

成功时返回 `TRUE`， 或者在失败时返回 `FALSE`。
