Hi all,
I'm trying to get data from several files using memory-mapped input,
i.e. I wrote the files with writeflex($outfile, $pdl1, $pdl2,...)
and now I try to get their contents into a set of arrays
($h[$i],$x[$i],$y[$i]) = mapflex($infile[$i], {READONLY => 1});
Unfortunately, all $h,$x,$y contain tidentical data, i.e. those from the
last file mapped, $infile[max($i)]
Either I didn't get the gist of memory mapping, or I'm doing something
wrong, probably both, but what ?
I also wrote a 4-line routine for the reading, using private variable
inside, but to the same result:
sub read_pdl{
my $h; my $x; my $y;
($h,$x,$y) = mapflex($ARGV[0], {READONLY => 1});
return($h,$x,$y);
}
I didn't really expect this to work better, but what am I doing wrong ?
N.B. using readflex instead, I get the expected results.
