Hi Zeev, If you look in main/php_streams.h, you'll see where I am coming from. Those rel_orig macros (as they stand now!) look like "thinkos" on my part.
The concept is that the original php_stream_xxx call that triggered the allocation is relayed to the memory manager, as well as listing the place where the actual allocation took place. Since there can be a number of levels of nested calls during stream_open_wrapper, I needed these macros rather than "plain" emalloc_rel because it didn't propogate the original file/line variables. If you can see a nicer way of achieving this, I'm all ears! --Wez. On 18/03/02, "Zeev Suraski" <[EMAIL PROTECTED]> wrote: > Are they really necessary?
