Thanks for the reply. Did you mean API declaration as the prototype interface?. If not, I have included the parameter declaration which is used in my script. I believe 't' is being passed since I used "encode("UTF-16LE", $profileName)" in the code. So I removed that also.

Following is the code snippet after making the above changes. Error message is also mentioned below: 

['WlanGetProfile' => 'IPNIPPI' => 'I'],

$profileName = unpack('J', pack('p', $profileName));
$API{ api}->Call($handle, $interface, $profileName, 0, $profileXml, 0,
+ 0));
