A cast must be applied to a pointer before anything else. In other words, you must apply scl_cast before scl_ptr, as illustrated by the following example: 

#pragma scl_function(GetUnicodeName)
#pragma scl_cast (GetUnicodeName, name, unsigned short*)
#pragma scl_ptr (GetUnicodeName, name,  "OUT",  PRIVATE)
#pragma scl_string (GetUnicodeName, name, 100)
