Question

I am using Net::SMPP package to handle SMPP protocol.
One of the protocol parameters should be NULL terminated string.
When I send it I do :

my $receipted_message_id = '111111'."\0";

When I receive it I strip last character.

Is any better way to work with “C String” in Perl ?

Answer 1

You could trim the terminating null with a simple substitution:

$receipted_message_id =~ s/\0$//;

…or simply chop() the last character:

chop $receipted_message_id;
