I am new to the perl interface for netCDF and I'm using the test.pl
script in the distribution to learn from. I want to get a variable's
attribute that is a string. I only see a way to get it as an ASCII
array. Currently I loop through the array with perl's chr to fix it,
but there must be a better way. What am I missing? Transcript follow.
rorik@stickley$ ncdump sample.nc
netcdf sample {
dimensions:
x = 2 ;
variables:
int x(x) ;
x:units = "meters" ;
data:
x = 1, 2 ;
}
rorik@stickley$ cat test.pl
#!/usr/bin/perl -w
use NetCDF;
my $ncid = NetCDF::open("sample.nc", NOWRITE);
my $varid = NetCDF::varid($ncid, "x");
NetCDF::attget($ncid, $varid, "units", \@var_att) == 0 or die;
print "@var_att\n";
foreach(@var_att) { print chr $_; }
print "\n";
rorik@stickley$ ./test.pl
109 101 116 101 114 115
