numbers getting changed (wrongly) with convert_to_long_ex()?

Hi. This is my first attempt to hack PHP, so if I'm making any stupid assumptions, I apologize... However, I'm having problems with adding on an ntohl() function. It seems that when I pass the argument 4294967295 (max size of ulong) to my ntohl() wrapper, some bits get lost or changed, as after a convert_to_long_ex(), i'm left with 2147483648 in the lval (this is when I cast the lval to an unsigned long value and do a debug php_error() message. This could be a problem if you're trying to interface with a binary TCP protocol, I think...Or is it just a problem with using long literals of that length/size in php source code? Attached is the source for the wrapper function, and the source I used to test. Any comments/suggestions appreciated, note that I'm not subscribed to the list yet, please CC me with replies. Thanks, Leon. -- ( Leon Breedt : ljb@debian.org ) ( Developer, Obsidian Systems : http://obsidianlinux.com )
