LinuxThreads & NPTL compatibility

[Trevor Lobban]

Hi,
    I've been searching for confirmation that LinuxThreads and NPTL are binary compatible for 'well written' applications (i.e sensible use of getpid and don't use any NPTL only features [process-shared etc.])

Can I build a thareded application on SLES 8 and expect it work on Red Hat AS 3 (or even AS 4)? The reason I ask is I notice the size of the pthread_cond_t has changed between SLES 8 and Red Hat AS 3 albeit the size increase appears all padding.

If the size is a problem, can I simply ensure that the memory I declare for my condition variables on SLES 8 has sufficient padding for the extra 36 bytes required by Red hat AS 3?

Any help is much appreciated.

Thanks,

Trevor
