# ps_delete

(PECL)

ps_delete -- Deletes all resources of a PostScript document

## 说明

bool ps_delete ( resource psdoc )

Mainly frees memory used by the document. Also closes a file, if it was not closed before with ps_close(). You should in any case close the file with ps_close() before, because ps_close() not just closes the file but also outputs a last line containing the PostScript comment with the number of pages in the document. Without this comment, a PostScript viewer may not show the number of pages properly.

## 返回值

如果成功则返回 `TRUE`，失败则返回 `FALSE`。
