The spec at https://learn.microsoft.com/en-us/windows/win32/fileio/reparse-points says: ... There is a limit of 63 reparse points on any given path. NOTE: The limit can be reduced depending on the length of the reparse point. For example, if your reparse point targets a fully qualified path, the limit becomes 31. */ Signed-off-by: Sebastian Feld <[email protected]> Diff: --- winsup/cygwin/include/cygwin/limits.h | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/winsup/cygwin/include/cygwin/limits.h b/winsup/cygwin/include/cygwin/limits.h index 204154da9072..728dfd47b5fc 100644 --- a/winsup/cygwin/include/cygwin/limits.h +++ b/winsup/cygwin/include/cygwin/limits.h @@ -43,7 +43,13 @@ details. */ #define __SEM_VALUE_MAX 1147483648 #define __SIGQUEUE_MAX 1024 #define __STREAM_MAX 20 -#define __SYMLOOP_MAX 10 +/* __SYMLOOP_MAX + https://learn.microsoft.com/en-us/windows/win32/fileio/reparse-points + ...
