Constants

• CSIDL_APPDATA: application-data folder identifier with value 26.
• SHGFP_TYPE_CURRENT: current-path selector with value 0.
• SHGFP_TYPE_DEFAULT: default-path selector with value 1.

Constant example

"windows/shell32" use
"control" use

{} () {} [
  CSIDL_APPDATA printStack _:;
  SHGFP_TYPE_CURRENT printStack _:;
  SHGFP_TYPE_DEFAULT printStack _:;
] "main" exportFunction

Expected Output During Compilation

SHGetFolderPathW (hwnd csidl hToken dwFlags pszPath -- result)

Writes one zero-terminated UTF-16 folder path into caller-supplied storage and returns one Int32 status.

• hwnd is one owner-window input of schema HWND.
• csidl selects the requested folder identifier.
• hToken is one raw pointer-sized input declared as Natx.
• dwFlags selects current-path or default-path lookup through the SHGFP_TYPE_* constants.
• pszPath is one raw pointer-sized input declared as Natx and represents caller-owned writable UTF-16 storage.
• On successful status, the written zero-terminated path remains in that caller-owned buffer.

Signature examples

Printing imported names during compilation shows the exact imported signatures.

"windows/shell32" use
"control" use

{} Int32 {} [
  @SHGetFolderPathW printStack _:;
  0
] "main" exportFunction

Expected Output During Compilation

{hwnd: {WND: (); unused: Int32;} Cref; csidl: Int32; hToken: Natx; dwFlags: Nat32; pszPath: Natx;} Int32 {convention: "";} codeRef
