refere include file : sys/utsname.h !
You can see if the macro __USE_GNU is set the char returned are 
'domainname' else the char are '__domainname' #@\[@~\
You know this function can do a apache segfault ?!
Becarful cuz domainename doesn't exist on freebsd !

there is the current (PHP-4.2.0RC1) code on : ext/posix/posix.c

/* {{{ proto array posix_uname(void)

return;

if (uname(&u) < 0) {
POSIX_G(last_error) = errno;
RETURN_FALSE;
}

if (array_init(return_value) == FAILURE) {
// TODO: Should we issue a warning here so we don't have ambiguity
// with the above return value ?
RETURN_FALSE;

[PHP-DEV] [Fwd: pg_exec function can be optimized]

all the time you use pg_exec you have to put the result of this function
into a 'PGresult *' and after the execution you have clear the pointer.
In big trafic your apache can take more memory. We can save more 1k per query

[PHP-DEV] question

2002-03-24 Thread Vergoz Michael (SYSDOOR) 

look this code :

char  buffer[MAXPATHLEN];
char *p;

if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "") == FAILURE)
return;

if((p = VCWD_GETCWD(buffer, MAXPATHLEN)) == NULL) {
POSIX_G(last_error) = errno;
RETURN_FALSE;
}

RETURN_STRING(buffer, 1);

in this code the char pointer 'p' is really needed ?

Hello list,
 
The function ImageTTFText do a anti-aliasing

Perhaps any function can stop the anti-aliasing for

does PHP support _s64 type ?

[PHP-DEV] paradoxal function

2002-09-19 Thread Vergoz Michael (SYSDOOR) 

hi list,

intval return a int (_s32) and the function 'convert_to_long_base' can 
save the 'zval' as _s64.
Well intval can't return a '_s64' type.

[PHP-DEV] and so... there is a security problem.

2002-09-19 Thread Vergoz Michael \(SYSDOOR\) 

Hi list,

i think that you have to return a _s64 per default, cuz for exemple i'm using some 
identification coded on _s64 if i jump 21 474 836 47, intval() will return to me a 
wrong number (normal) but i _can't_ know if that that number is a valid _s64 (_s64) 
and there can have some big security problems

Exemple:

$id = intval($_GET['id']);
$query = "
SELECT
\"proute\"
FORM 
\"polom\"
WHERE
    id = $id
";

Best regards,

WHAT ?!
I never refering to typedef anyway !!
_s64 are nothing in common with typedef !

_s64 is a double words :

linux/types.h:113:typedef   __s64   int64_t;

descript@fabienne:/usr/include$ grep -rn s64 * | wc -l
 85
descript@fabienne:/usr/include$


Well, i think that you have to learn C hmmm...
