Remarks

The RTL_CONSTANT_STRING macro creates a string or Unicode string structure to hold a counted string.

STRING RTL_CONSTANT_STRING(
  [in]  PCSZ SourceString
);

UNICODE_STRING RTL_CONSTANT_STRING(
  [in]  PCWSTR SourceString
);

RTL_CONSTANT_STRING returns either a string structure or Unicode string structure.

The RTL_CONSTANT_STRING macro replaces the RtlInitAnsiString, RtlInitString, and RtlInitUnicodeString routines when passing a constant string.

You can use RTL_CONSTANT_STRING to initialize global variables.
