PHP 忒聊 綴豖 ヶ輛 php_stream_is (no version information, might be only in CVS) Description php_stream_is() returns 1 if stream is of the type specified by istype, or 0 otherwise. 桶跡 43-1. Values for istype Value Meaning PHP_STREAM_IS_STDIO The stream is implemented using the stdio implementation PHP_STREAM_IS_SOCKET The stream is implemented using the network stream implementation PHP_STREAM_IS_USERSPACE The stream is implemented using the userspace object implementation PHP_STREAM_IS_MEMORY The stream is implemented using the grow-on-demand memory stream implementation 蛁: The PHP_STREAM_IS_XXX "constants" are actually defined as pointers to the underlying stream operations structure. If your extension (or some other extension) defines additional streams, it should also declare a PHP_STREAM_IS_XXX constant in it's header file that you can use as the basis of this comparison. 蛁: This function is implemented as a simple (and fast) pointer comparision, and does not change the stream state in any way.
