Subject: mmap to fixed adr
Date: Sun, 19 Jun 2011 14:02:49 +0200	[thread overview]
Message-ID: <4DFDE569.9060105@openbios.org> (raw)

Hi,

is there a VA range in userspace which is always safe for mmap() with 
fixed adr? (x86_64 mostly)

I.e. a VA range where mmap() or ld will never map memory.

I know I can try particular fixed adr with mmap() and check if the 
mapping succeeds. However this is not what I want. I want mmap() to stay 
clear of certain ranges and map memory there myself.

Regards
.....Volker
