diclophis / contig_alloc.c
Created January 2, 2011 22:27 — forked from karthick18/contig_alloc.c
/*
* A simple on-demand based mmap alloc-only proof-of-concept to just check out the possibilities of having a
* single giant MAP_FIXED allocation for a process that may not need to call free at all and just work with a
* contiguous allocation space
*
* A mmap contiguous hole space is reserved with a PROT_READ and then individual pages overridden with
* PROT_WRITE on page faults in sigsegv handler which mmaps the faulting address space.
*
* As a test, a 1 GIG file is created and then read into the memory allocated from the contiguous vma which is a
* brain-dead linear allocator from the address space as there are no requirements to free memory here.

# you should load the file and save the edges
end
# implementation of Enumerable is bonus points
