php_stream_can_cast -- Determines if a stream can be converted into another form, such as a FILE* or socket

## Description

int php_stream_can_cast ( php_stream * stream, int castas )

> Notatka: Although this function will not perform the conversion, some internal stream state *might* be changed by this call.

> Notatka: You must explicitly compare the return value of this function with one of the constants, as described in php_stream_cast().
