UnixMmap is an alternative to the Julia standard library's Mmap, with the purpose of
exposing the Unix memory-mapping interface.
Installation and loading is as easy as:
pkg> add UnixMmap
julia> using UnixMmapA file can be memory mapped (read-only by default) by giving the filename and the Array
type (optionally with dimensions to give a shape):
julia> UnixMmap.mmap("arbitrary.dat", Vector{Float64})
192-element Vector{Float64}:
0.0
0.0
⋮
0.0
0.0
julia> UnixMmap.mmap("arbitrary.dat", Matrix{Float64}, (64, 3))
64×3 Matrix{Float64}:
0.0 0.0 0.0
0.0 0.0 0.0
⋮
0.0 0.0 0.0
0.0 0.0 0.0while an anonymous memory map can be created by instead specifying the Array type and
dimensions:
julia> UnixMmap.mmap(Matrix{Float64}, (128, 3))
128×3 Matrix{Float64}:
0.0 0.0 0.0
0.0 0.0 0.0
⋮
0.0 0.0 0.0
