multi-threading in eCos and Linux

multi-threading in eCos and Linux

[mctim]

Hi,

I am going to write a cross-platform multithreading program in eCos and Linux, 
as I know, both eCos and Linux are support POSIX thread (p_thread) and eCos 
also have some API  (cyg_thread) to handle multi-threading. I want to write an 
crossplatform compatible program which suit to eCos and Linux. So I want to 
use POSIX thread to develop this program. But I afraid the performance of 
POSIX thread in eCos is not good as cyg_thread in eCos. Could you suggest me 
that which threading API in eCos is prefered( p_thread or cyg_thread)? Thanks 
a lot.

Regards,
Tim

This isn't really appropriate to the maintainers list but I'll reply anyway.

While it's true that the native cyg_threads stuff is the most efficient, 
you'll find that eCos is a sufficiently lightweight operating system 
anyway that the very small overhead of using POSIX threads will not have 
any real impact. If your requirements are that it is cross platform, then 
POSIX threads are definitely the way to go.
