Hi,
I found another problem with Semaphores between FreeBSD and Linux.
Attached is my test project. Again, it is similar code used in tiOPF.
For some reason under FreeBSD, it *always* zeros the variable that holds
the Max Pool Size value passed in to sem_init()'s third parameter. This
means that if I try and us that variable anywhere after the sem_init()
call, like when I want to destroy the semaphore, I can't because the
variable now holds the value 0.
FPC's definition of the semaphore struct is probably wrong for FreeBSD.
Currently, it's:
sem_t = cint;
You are in so far right that the declaration is incorrect, but in trunk
it looks like this:
=== code begin ===
sem_t_rec = record end;
sem_t = ^sem_t_rec;
=== code end ===
So that it resembles the declaration of sem_t in the headers of FreeBSD 7:
=== code begin ===
typedef struct sem * sem_t;
=== code end ===
Nevertheless this needs to be changed...
Regards,
Sven
