[ion] 52726: [RTL]: Implement RtlDosPathNameToRelativeNtPathName_U_WithStatus, RtlDosPathNameToRelativeNtPathName_U, RtlDosPathNameToNtPathName_U_WithStatus. [RTL]: Reimplement RtlDosPathNameToNtPa...
Author: ion Date: Mon Jul 18 13:22:09 2011 New Revision: 52726
URL: http://svn.reactos.org/svn/reactos?rev=52726&view=rev Log: [RTL]: Implement RtlDosPathNameToRelativeNtPathName_U_WithStatus, RtlDosPathNameToRelativeNtPathName_U, RtlDosPathNameToNtPathName_U_WithStatus. [RTL]: Reimplement RtlDosPathNameToNtPathName_U to use UNICODE_STRING semantics. [RTL]: Fix RtlGetFullPathName_Ustr. [RTL]: RtlGetFullPathName_U remains based on the legacy non-UNICODE_STRING mechanism, but it's too complex to attempt changing for now.
