First thing you should do when you are confronted with this type of
problem, is look in the actual dll for the function. Had you done so,
you would have seen that GetRoleText doesn't exist.
There is, however a GetRoleTextA and a GetRoleTextW.

Another clue to this would be to look in the headers where GetRoleText
is defined.
 There you would see that it is defined as GetRoleTextA or W,
depending on the default size of your chars.

Windows has many functions defined this way, so always check for A/W
versions if there is text involved.
