[PATCH] kernelbase: Implement PathCchAddBackslash()/PathCchAddBackslashEx()
Signed-off-by: Nikolay Sivov <nsivov(a)codeweavers.com> --- Added separate source file - on Win10 older path manipulation functions from shlwapi are reimplemented in kernelbase.dll, so we'll need to move them there too in order to avoid forwarding to shlwapi. .../api-ms-win-core-path-l1-1-0.spec | 4 +- dlls/kernelbase/Makefile.in | 3 +- dlls/kernelbase/kernelbase.spec | 4 +- dlls/kernelbase/path.c | 67 ++++++++++ dlls/kernelbase/tests/path.c | 136 +++++++++++++++++++++ include/pathcch.h | 2 + tools/make_specfiles | 1 + 7 files changed, 212 insertions(+), 5 deletions(-) create mode 100644 dlls/kernelbase/path.c diff --git a/dlls/api-ms-win-core-path-l1-1-0/api-ms-win-core-path-l1-1-0.spec b/dlls/api-ms-win-core-path-l1-1-0/api-ms-win-core-path-l1-1-0.spec index cb10d89773..287c5d61d9 100644 --- a/dlls/api-ms-win-core-path-l1-1-0/api-ms-win-core-path-l1-1-0.spec +++ b/dlls/api-ms-win-core-path-l1-1-0/api-ms-win-core-path-l1-1-0.spec @@ -1,7 +1,7 @@ @ stub PathAllocCanonicalize @ stub PathAllocCombine -@ stub PathCchAddBackslash -@ stub PathCchAddBackslashEx +@ stdcall PathCchAddBackslash(wstr long) kernelbase.PathCchAddBackslash +@ stdcall PathCchAddBackslashEx(wstr long ptr ptr) kernelbase.PathCchAddBackslashEx @ stub PathCchAddExtension @ stub PathCchAppend @ stub PathCchAppendEx diff --git a/dlls/kernelbase/Makefile.in b/dlls/kernelbase/Makefile.in index 74df98ce2d..a7db45e4c1 100644 --- a/dlls/kernelbase/Makefile.in +++ b/dlls/kernelbase/Makefile.in @@ -1,4 +1,5 @@ MODULE = kernelbase.dll C_SRCS = \ - main.c + main.c \ + path.c diff --git a/dlls/kernelbase/kernelbase.spec b/dlls/kernelbase/kernelbase.spec index aa67372cf5..eafe5ab9dd 100644 --- a/dlls/kernelbase/kernelbase.spec +++ b/dlls/kernelbase/kernelbase.spec @@ -1029,8 +1029,8 @@ @ stdcall PathAppendW(wstr wstr) shlwapi.PathAppendW @ stdcall PathCanonicalizeA(ptr str) shlwapi.PathCanonicalizeA @ stdcall PathCanonicalizeW(ptr wstr) shlwapi.PathCanonicalizeW -# @ stub PathCchAddBackslash -# @ stub PathCchAddBackslashEx +@ stdcall PathCchAddBackslash(wstr long) +@ stdcall PathCchAddBackslashEx(wstr long ptr ptr) # @ stub PathCchAddExtension # @ stub PathCchAppend # @ stub PathCchAppendEx diff --git a/dlls/kernelbase/path.c b/dlls/kernelbase/path.c new file mode 100644 index 0000000000..373c34e979 --- /dev/null +++ b/dlls/kernelbase/path.c @@ -0,0 +1,67 @@ +/* + * Copyright 2018 Nikolay Sivov + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
