(no version information, might be only in CVS)php_stream_is -- Determines if a stream is of a particular type

Description

int php_stream_is (php_stream * stream, int istype)


php_stream_is() returns 1 if stream is of the type specified by istype, or 0 otherwise.

Таблица 1. Values for istype
ValueMeaning
PHP_STREAM_IS_STDIOThe stream is implemented using the stdio implementation
PHP_STREAM_IS_SOCKETThe stream is implemented using the network socket implementation
PHP_STREAM_IS_USERSPACEThe stream is implemented using the userspace object implementation
PHP_STREAM_IS_MEMORYThe stream is implemented using the grow-on-demand memory stream implementation

Замечание: 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.

Замечание: This function is implemented as a simple (and fast) pointer comparison, and does not change the stream state in any way.

See also php_stream_cast() and php_stream_can_cast().
