Re: [Haskell-cafe] FFI question

Bottom line is how can I do arithmetic (addition) on two #const's ??? I can hard code a "3" => nasty solution ... Kind thanks, Vasili On Tue, Sep 9, 2014 at 10:53 PM, Vasili I. Galchin wrote:

oops ... let me check ..

on the other hand after rereading man page on POSIX mlockall I noticed that "flags" formal parameter .. .I noticed that can be OR'd .. hence I want to OR MCL_CURRENT and MCL_FUTURE ... fix this then ...

back to helping Ukraina before V.V.Putin does more nastiness ....

Kind thanks,

Did a find/grep under my posix-realtime directory .. no definition of MCL_CURRENT, MCL_FUTURE or MCL_CURRENTandFUTURE!! But If I comment out the case arm MCL_CURRENTandFUTURE in my LockMem.hsc file and run "cabal build" from the directory where my *.cabal file lives .. clean compile ... Sigh!??!!

The fact that they start with uppercase tells me that they are from C, not Haskell. The implication of their relationship with mlockall is that they come from a related system header file, namely .

I note that neither my FreeBSD nor my OS X system defines MCL_CURRENTandFUTURE in /usr/include/sys/mman.h, although the other two are defined.
