Accessing an array of structs

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hello, I`m trying to access an array of structs. The ``for my $struct (@structs)'' way works, but I don`t know how to directly access a struct in the array. Saying sth. like ``$structs[0]->name'' for instance gives an error ("Can't call method "name" on unblessed reference"). Is there a way to access it directly? If so please tell me, I`ll name my first child after you if you do :) thanks in advance Joern

I think you want `$structs[0]->{name}` (the `$structs[0]->name` looks to Perl like `$structs[0]->name()`, that is, a method call on the first element of `@structs`).	[reply] [d/l] [select]

What are those "structs"? Real C structs passed by some C binding or just hash refs? In the first case, the issue is more complicated and may involve unpack and a few tweaks until the right data is visible to Perl (not necessarily in a portable way). In the second change, replace `$structs[0]->name` with `$structs[0]->{name}` and you'll be fine.	[reply] [d/l] [select]
