#25235 [NEW]: win32api problem in arguments

From: fgarcia at uef dot es Operating system: Windows 2000 PHP version: 4.3.2 PHP Bug Type: Unknown/Other Function Bug description: win32api problem in arguments Description: ------------ I need to use a dll external function. My code in php 4.2.3 was: ------------------ w32api_register_function("MYLIB.DLL", "MYFUNC", "long"); $attr1="string1"; $attr2="string2"; $attr3="string3"; $attr4="string4"; $attr5="string5"; $attr6=long2Str(2);// long $iError=MYFUNC($attr1,$attr2,$attr3,$attr4,$attr5,$attr6); $iRtn=str2Long($siRtn); -------------- The code works. Now (php 4.3.2) my code is: -------------- $api = new win32(); $api->RegisterFunction("int MYFUNC(string attr1, string attr2, string attr3, string attr4, string attr5, int &attr6) From MYLIB.DLL"); $attr1="string1"; $attr2="string2"; $attr3="string3"; $attr4="string4"; $attr5="string5"; $attr6=2;// long $iError=$api->MYFUNC($attr1,$attr2,$attr3,$attr4,$attr5,$attr6); ------------------- and php crashes. I've traced the dll call and I've seen that arguments aren't pass well to the dll. In PHP 4.2.3 version, first argument (attr1) offsets 0x04 bytes (in the call stack) but in 4.3.3 version the same first argument offsets 0x08 bytes. It seems that PHP 4.3.3 version puts an extra (???) attribute in the call stack. -- Edit bug report at http://bugs.php.net/?id=25235&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=25235&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=25235&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=25235&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=25235&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=25235&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=25235&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=25235&r=support Expected behavior: http://bugs.php.net/fix.php?id=25235&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=25235&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=25235&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=25235&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=25235&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=25235&r=dst IIS Stability: http://bugs.php.net/fix.php?id=25235&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=25235&r=gnused
