Protection API - SDP_GetRegistrationName

SDP_GetRegistrationName

The SDP_GetRegistrationName function is used to read in names of registered users based on license key.

  For C++:

        int SDP_GetRegistrationName(
            char *szRegistrationName, // address of buffer for users name
            int iMaxLen               // maximum number of characters to copy
            );
  For Delphi:
        function SDP_GetRegistrationName(
            szRegistrationName :PChar  // address of buffer for users name
            iMaxLen :Integer           // maximum number of characters to copy
            ): Integer;  

Parameters

szRegistrationName

[in] points to a buffer, where users name will be copied to.

iMaxLen

[in] sets the maximum numbers of characters to copy.

Return Values

If users name is copied to the buffer, the number of copied bytes will be returned, not including last zero (ASCII). If there will be a problem, or license key is incorrect, zero will be returned.

Remarks

The size of buffer shoud be bigger than 40, or the function will possibly fail.

Example

for C/C++

#include "SDProtector.h"

//...

void GetUserName()
{
    char szUserName[42];
    int  iMaxLen=42;

    memset(szUserName,0,iMaxLen);
    if(SDP_GetRegistrationName(szUserName,42))
    {
       ::MessageBox(NULL,szUserName,"Program registered to",MB_ICONINFORMATION); 
    } 
    else
    {
       ::MessageBox(NULL,"This an unregistered version","Error",MB_ICONINFORMATION); 
    } 

}

for Delphi

        
procedure GetUserName;
var szUserName:array[0..41] of char;
begin
   fillchar(szUserName,42,#0);

   if SDP_GetRegistrationName(@szUserName[0],42) <> 0 then
      MessageBox(0,@szUserName[0],'Program registered to', MB_ICONINFORMATION);
   else
      MessageBox(0,'This an unregistered version', 'Error', MB_ICONINFORMATION);
end;
