Hi, I have written .pm file, that takes the key value pair as input and populates a hash. This code is called repeatedly from a C program that embeds this perl code. e.g. 
for (int i = 0; i < 10; i++)
{
...
perl_call_pv("PerlCode::addKeyValue", G_EVAL|G_SCALAR);
...
}

[download]
and the perl code is : 
sub addKeyValue
{
   ($key, $value} = @_;
   push @{${$self->{$hash}}{$key}}, $value;
}

[download]
Now, I want to write another function in Perl, that would modify this hash, (say add another key - value) and I want to return this hash back to the C code. How do I do this? Thanks in advance, Raj
