(no version information, might be only in CVS)
This function is equivalent to calling
php_stream_cast()
with
ret
set to NULL and
flags
set to 0. It returns
SUCCESS
if the stream can be converted into the form requested, or
FAILURE
if the conversion cannot be performed.
注意 Although this function will not perform the conversion, some internal stream state *might* be changed by this call.
注意 You must explicity compare the return value of this function with one of the constants, as described in php_stream_cast() .
