Subject: php_stream_opendir again!
From: frak@totalise.co.uk ("Mikey")

Hello again,

Well, two books (Advanced PHP Programming [very good] & Building Custom PHP
Extensions [not so good]) and a bit of experimentation later, I have
narrowed my problem down to the following:

If I call php_stream_opendir from within an exposed function it works fine
but dies with the segfault as earlier described when I try to call it from a
helper function. For example:

PHP_FUNCTION(tmpl_reload)
{
	if (ZEND_NUM_ARGS() != 0) {
		WRONG_PARAM_COUNT;
	}
	php_stream *base_dir = NULL;
	php_stream_context *context = NULL;
	if (TMPL_G(template_dir) != NULL)
		base_dir = php_stream_opendir (TMPL_G(template_dir),
ENFORCE_SAFE_MODE|REPORT_ERRORS, context);
	if (base_dir)
	{
		RETURN_BOOL (1);
	}
	else
	{
		RETURN_BOOL (0);
	}
}

This function works fine and always returns true/1, however:

int do_reload ()
{
	// My declares
	php_stream *base_dir = NULL;
	php_stream_context *context = NULL;
	int count = 0;

	// Zend declares
	TSRMLS_FETCH();

	// Start from scratch
	TMPL_G(tmpl_loaded) = 0;
	if (TMPL_G(template_dir) != NULL)
		base_dir = php_stream_opendir (TMPL_G(template_dir),
ENFORCE_SAFE_MODE|REPORT_ERRORS, context);
	TMPL_G(tmpl_dir_valid) = (base_dir) ? 1 : 0;
	return 1;
}

Causes a segfault.  So, my question is as follows - is there a specific way
to declare helper functions so that they have whatever is available to the
module functions so that I can avoid this segfault?

Regards,

Mikey
