1-How can I create natives?
2-How can I return integers, handles, floats, etc.?
3-How can I return strings? (I think I have to use referance thing?!?!)
4-How can I get/return arrays. (Float array, string array, etc.)
5-What does 'MarkNativeAsOptional()' do? Do I have to use it? How can I use it?

I want to add some natives to SStocks. I hope I can help you code easier.

From my MYSQL manager plugin:

PHP Code:

public bool:AskPluginLoad(Handle:myself, bool:late, String:Error[])
{
  // General
  CreateNative("DB_GetColumnId", Db_GetColumnId);
  CreateNative("DB_EnableId", Db_EnableColumn);
  CreateNative("DB_DisableId", Db_DisableColumn);
  CreateNative("DB_ColumnType", ReturnColumnType);
  CreateNative("DB_GetHandle", DB_ReturnHandle);
  //CreateNative("DB_CreateRow", DB_CreateNewRow);
  
  CreateNative("DB_SetInfo", SetColumnInfo);
  CreateNative("DB_SetInfoString", SetColumnInfoString);
  
  CreateNative("DB_GetColumn", GetColumnInfo);
  CreateNative("DB_GetColumnString", GetColumnInfoString);

  return true;
} 


A simple native:

PHP Code:

//Client, column
public GetColumnInfo(Handle:plugin,argc){
    if(argc==2){
        new client = GetNativeCell(1);
        if(client > MAXPLAYERS )
            ThrowNativeError(0, "Invalid client!");
            
        new column = GetNativeCell(2);
        if(column > Totalcount )
            ThrowNativeError(0, "Invalid column!");            
        
        switch(  GetColumnType(column) ){
            case DB_INT, DB_FLOAT: {
                return GetArrayCell( GetArrayCell(adt_adress,column) , client);
            }
            case DB_STRING: ThrowNativeError(0, "Column is not a string!");
        }        
    }
    return -1;
}

//Client, column, sting, maxsize
public GetColumnInfoString(Handle:plugin,argc){
    if(argc==4){
        new client = GetNativeCell(1);
        if(client > MAXPLAYERS )
            ThrowNativeError(0, "Invalid client!");
            
        new column = GetNativeCell(2);
        if(column > Totalcount )
            ThrowNativeError(0, "Invalid column!");            
        
        switch( GetColumnType(column) ){
            case DB_INT, DB_FLOAT: ThrowNativeError(0, "Column is not a int/float!");
            case DB_STRING: {
                 new size = GetNativeCell(4);
                 new String:temp[size];
                 GetArrayString( GetArrayCell(adt_adress,column) , column ,temp, size);
                SetNativeString(3, temp, size);
            }
        }
    }
}

Thanks Bail. I didn't saw that and looked at "Natives (SourceMod Development)"
