RtlOemStringToUnicodeString function (ntifs.h)
The RtlOemStringToUnicodeString routine translates a given source string into a null-terminated Unicode string using the current system OEM code page.
Syntax
NTSYSAPI NTSTATUS RtlOemStringToUnicodeString(
PUNICODE_STRING DestinationString,
[in] PCOEM_STRING SourceString,
[in] BOOLEAN AllocateDestinationString
);
Parameters
DestinationString
Pointer to a caller-allocated buffer to receive the translated string. If AllocateDestinationString is FALSE, the caller must also allocate a buffer for the Buffer member of DestinationString to hold the null-terminated Unicode string. If AllocateDestinationString is TRUE, RtlOemStringToUnicodeString allocates a buffer large enough to hold the string, passes a pointer to it in Buffer, and updates the length and maximum length members of DestinationString accordingly.
[in] SourceString
Pointer to the OEM string to be translated to Unicode.
[in] AllocateDestinationString
Set to TRUE if RtlOemStringToUnicodeString should allocate the buffer space for the DestinationString, FALSE otherwise. If this parameter is TRUE, the caller is responsible for freeing the buffer when it is no longer needed by calling RtlFreeUnicodeString.
Return value
RtlOemStringToUnicodeString returns STATUS_SUCCESS if it returns a translated string at DestinationString. Otherwise, no storage was allocated and no conversion was done.
Remarks
RtlOemStringToUnicodeString translates the given source string using the OEM code page that was installed as the current system code page at system boot time.
This routine does not modify the source string. It returns a NULL-terminated Unicode string.
