It was discovered that this undocumented behaviour was being relied on by a long deprecated Rust stdlib function.
In confirming this behaviour applied to both
GetUserProfileDirectoryW
andGetUserProfileDirectoryA
, I found that theA
function, unlike theW
function, was not returningTRUE
on success. Instead it also returns the size written to the buffer. I'm not sure if that part should be documented so I just changed the success case to nonzero and failure to zero.
