Description:
------------
I`m trying to compile php with sfio lib. for stdio bug workaround.

It configures and  compiles is fine, but simple test.php script shows:
Fatal error: Call to undefined function:  fread() in /usr/home/kuzmich/apache/php-4.3.8/sapi/cli/test.php on line 3

Reproduce code:
---------------
test.php:
<?
    $p = fopen("./test".microtime(),"w+");
    $buf = fread ($p,10);
    fclose($p);
    echo $buf;
?>

configure script:
CFLAGS="-I/home/kuzmich/sfio/include -I/usr/include -I/usr/local/include -I/opt/sfw/include" \
CXXFLAGS="-I/home/kuzmich/sfio/include -I/usr/include -I/usr/local/include -I/opt/sfw/include" \

Can you confirm that sfio does something along the lines of:
#define fread   sfio_fread

in its headers?
 [2004-08-12 13:38 UTC] pk at nodex dot ru 
Sfio have lines:
#define fread                   _stdfread

Difintion of stdfread:
extern ssize_t  _stdfread _ARG_((Void_t*, size_t, size_t, Sfio_t*));
 [2004-08-12 13:57 UTC] wez@php.net 
So, the fread() function will be callable from your script as _stdfread() instead ?

We need to use the NAMED variety of the PHP_FUNCTION and PHP_FE macros to avoid this issue.
 [2004-08-12 14:11 UTC] pk at nodex dot ru 
SFIO redefine fopen call with _stdfread in precompilation.
And any C sources compilling good with sfio.

SFIO is transparent for sources.

Can you give me the patch for this issue?
 [2004-08-12 14:35 UTC] wez@php.net 
If I had the time to patch it, I would have done it already.
Maybe someone else will do it in the meantime.
 [2004-08-12 14:53 UTC] pk at nodex dot ru 
Please find your time for this.
I work with PHP 4.2.3 for now and i can`t upgrade because this 
issue is have a place.

http://tony2001.phpclub.net/dev/tmp/fread.diff - probably this may help (diff was done against HEAD).

Change the line in ext/zlib/zlib.c with 
PHP_FALIAS(gzread,		fread,			NULL)
to 
PHP_NAMED_FE(gzread,		php_if_fread,		NULL)
 [2004-08-17 07:26 UTC] tony2001@php.net 
It seems, that http://tony2001.phpclub.net/dev/tmp/fread.diff solves the problem, but currently I got no possibility to test it myself.
Could anyone (with sfio installed) test it, plz?
The patch was done against HEAD, but similar patch will work with 4.3.9 too.
 [2004-10-01 10:14 UTC] sniper@php.net 
Try the patch again using latest CVS snapshot.
