would it then make sense for all outside filters to use these routines? Due to

Hi all,
I stand corrected.
I just created a test project and inspected the assembler for the output
and it turns out that the CRT does share state when statically linked

The point is to visually distinguish the function from free(). After all, if

The longer function name indicates that it is special and has a particular use.

What version of HDF5 are you using? Are you using H5Pset_libver_bounds() to set
a particular version of the file format (e.g.: H5F_LIBVER_LATEST)?
Can you reduce this to a small C program that demonstrates the problem?
Thanks,

Hi Andrey,
I'll create an issue for this. We have a Windows layer that substitutes Win32
equivalents for some POSIX commands and it should be straightforward to use
SetEnvironmentVariable() on Windows.

Hi all,
Sorry I've missed most of this discussion, but HDF5 1.10.1 checks an
environment variable that you can use to disable file locking
(HDF5_USE_FILE_LOCKING). Setting this to "FALSE" disables all file lock calls.

Is HDF5_USE_FILE_LOCKING applied at configure time, build time, or run time?

ion that the OS
typically discards those freed pages easily when other processes need the
