Hello,

What approaches can be used in Perl for receiving/sending data to a server written in C that expects said data to be exactly delimited according to C types ? Like: 

struct Result {
DWORD var1;
BYTE  var2;
WORD  var3;
short var4;
int   var5;
float var6;
};

The server expects the exact data lengths for each variable because it simply 'shifts' the bytes as they come in into its appropriate structures.

Are there recipes to shape Perl internal data representation to fit C structures before sending them in the network ?

Same for receiving C data: Are there recipes to read in C data and use Perl hashes based on the C structure definition ?

Is there a Perl module (or modules) that can help ?

Thanks !
