Thanks !
Martins source now does compile with
uses baseunix and
fpsignal(), fpsigemptyset(), fpsigaddset() and fpsigprocmask(),
fpwrite(), ... :)
but there are some more libc functions used, that I did not yet find an
equivalent for::
e.g.:
libc.setitimer(),
As sem_post does not seem to be exported somewhere, I defined sem_post
like this:
function sem_post(__sem:Psem_t):longint;cdecl;external;
(also alike for sem_init() and friends)
it does compiler and link, but I_m not sure if it will work. I'd need to
do some additional porting, as this function has different parameters
from the sem_init() Martin uses (var parameter for the __sem argument).
Any further tips ?
@Martin:
what is the complicated thread save stuff with sys_semdestroy()
necessary for ?
Would it not be useful to use a Futex instead of a sema ?
@Marco:
Direct Futex calls of course are only available with libc, but I suppose
there are some baseunix things, as futex implicitly is used by by the
ptrhead library with thread-semaphores.
Thanks to both of you,
