fopencookie.phpt

php-4.4.7学习linux时下载的源代码

--TEST--
fopencookie detected and working (or cast mechanism works)
--FILE--
<?php
# vim600:syn=php:

/* This test verifies that the casting mechanism is working correctly.
 * On systems with fopencookie, a FILE* is created around the user
 * stream and that is passed back to the ZE to include.
 * On systems without fopencookie, the stream is fed into a temporary
 * file, and that temporary file is passed back to the ZE.
 * The important thing here is really fopencookie; the glibc people
 * changed the binary interface, so if haven't detected it correctly,
 * you can expect this test to segfault.
 *
 * FIXME: the test really needs something to fseek(3) on the FILE*
 * used internally for this test to be really effective.
