The following slightly modified script produces a set of gif files given a data file and a site ID as arguments. So, not surprisingly, the library can be called from Perl on Linux platform quite easily.

Regarding using the library on Windows, note the following from the GVBOX page - http://trmm-fc.gsfc.nasa.gov/trmm_gv/software/gvbox/gvbox.html:

It is assumed that you have a working Unix operating system and that you can compile C, C++ and Fortran source code, and that you have perl and optionally bison and flex.

I can't find any evidence that it has been ported to Windows - which doesn't mean that it hasn't been or that it would be difficult to do.

#!/usr/bin/perl
#
use Inline C => DATA =>
    INC => '-I/usr/local/trmm/GVBOX/include' =>
    LIBS => '-L/usr/local/trmm/GVBOX/lib -lrsl';

    my $file = shift or die "USAGE: radar.pl file ID\n";
    my $id = shift or die "USAGE: radar.pl file ID\n";
    my_test($file, $id);

__END__

#include "rsl.h"

int my_test(char* file, char* id) {
    Radar *radar;
    radar = RSL_anyformat_to_radar(file, id);
    RSL_load_refl_color_table();
    RSL_volume_to_gif(radar->v[DZ_INDEX], "dz_sweep", 400, 400, 200.0)
+;
    return(0);
