Converts a code page number into a code page represented as a UniChar string that is acceptable as input to the UniCreateUconvObject.

#include <uconv.h>

ULONG        ulCodepage;   /*  A code page as returned from DosQueryCp. If the value is zero, the current process code page value is used to determine the returned Unicode string. */
UniChar     *ucsCodepage;  /*  A buffer for placing the Unicode string. */
size_t       n;            /*  Size of the ucsCodepage buffer in characters. This should be at least 12 Unicode characters. */
int          result;

result = UniMapCpToUcsCp(ulCodepage, ucsCodepage,
           n);
