Return Value

If the function succeeds, the return value is the starting address of the mapped view.

If the function fails, the return value is NULL. To get extended error information, call GetLastError.

At line 5, the query is executed and the result is assigned to the array. When I print the elements of playerLst array only 11 player names are printed(not what I expect. It has to print 99 names since each country has 11 players and there are 9 cty's).
