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.
