[fpc-devel] Why FreeBSD sem_init() works different to Linux?

[Graeme Geldenhuys]

Hi,

OK, now that we established that semaphores are broken in FreeBSD using
FPC 2.6.0 and the upcoming FPC 2.6.2. I'm looking for an alternative.

An alternative for two reasons.
  - I hate IFDEF code, and the semaphore code between Linux, FreeBSD
    and Windows are different.
  - Semaphore sem_t structure is incorrectly defined for FreeBSD, so
    I'll have to implement a special case for that platform.

Semaphore functionality seems pretty simple though, so I am thinking of
creating my own Object Pascal based cross-platform semaphore - no low
level code or OS specific library API's.

It case I'm overlooking something critical, has anybody else done
something like this. If so, anybody willing to share that code - saving
me some time in developing, unit testing and debugging my own Object
Pascal based semaphore.

Regards,
  - Graeme -
