But, to summarize then chances for generic units are slim. The unportable garbage "linux" unit is then the only solution, and then hope that cut down linuxes don't cut it out. > > Then solaris and Haiku as the other unices must be checked. > Solaris at least has man pages for those functions.

If such a recent Darwin doesn't have it, then IMHO it is not an option now. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

And usually it only works for root. IOW not all Unices might implement it, which is more or less the rule of thumb to get into one of the portalbe units (unix,baseunix) Sometimes exceptions to this rule are made (e.g. for UUID functions) when the function are found to be implemented on all unix platforms. I checked and they (+ the corresponding unlock) are in FreeBSD5+, so FreeBSD is no problem (MCL_CURRENT and MCL_FUTURE are the mandatory flags by Posix, and FreeBSD only supports those) I saw some hints on the web that OS X doesn't support it (but it should be checked against 10.3/10.4+ since afaik those implement a lot more calls due to synchronization with FreeBSD5) Then solaris and Haiku as the other unices must be checked. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
[fpc-devel] mlockall() unit libc
hi all, i need the mlockall() call (unit libc) in my realtime apps on linux i386 to lock the address space of the process. Works, but unit libc has no future and it's the only function i need from this unit. I would like to add this call to another unit (unix? baseunix?). Can I look at the fpmmap() implementation or are there better "examples" ? Thanks for any hints. kisda signature.asc Description: OpenPGP digital signature ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
