Re: Discover multiple processors programmatically?

Is there an API that would allow me to discover the availability of

sysctl(3) ?

If so, is it somewhat standard -- would it work on say, Linux?

it should work on any 4.4BSD derivative, the linux variant sysctl(2) is similar
with some macros and conditional compilation, you might be able to use it on both.


I am parallelizing an application and would like to have two- and four-processor versions
of some computationally intense code.

sounds good

Anyone know of such an API, particularly one that is someone platform-
independent?

anyone got a better idea ?
