Hi, Ed,

The default is on--it intends to help "beginners".  So, you need
to turn it off per run via H5Eset_auto().  It is also possible for
third party libraries (e.g., netCDF) to turn it off during the setup
stage if they feel their users do not need the automatic error messages.

Hello HDF5 People!

When I cause an HDF5 error  get this kind of printout:

HDF5-DIAG: Error detected in HDF5 library version: 1.6.1 thread 0. Back trace follows.

  #000: H5F.c line 2357 in H5Fcreate(): unable to create file
    major(04): File interface
    minor(15): Unable to open file
  #001: H5F.c line 1914 in H5F_open(): unable to open file
    major(04): File interface
    minor(15): Unable to open file
  #002: H5FD.c line 830 in H5FD_open(): open failed

  #003: H5FDsec2.c line 321 in H5FD_sec2_open(): unable to open file
    major(04): File interface
    minor(15): Unable to open file

This has been very helpful to me, but I would like to turn it off. I
see the H5Eset_auto() function, but I wonder if I really have to turn
this off every time I use the HDF5 library?

Or did I somehow turn this on by default when I built my copy of HDF5,
and for other people it will be off by default?

Thanks!

Ed

Can you tell me more about turning it off during the setup stage?

What do you mean by setup stage? Do you mean when HDF5 is first built?
Or something else?

Thanks!
