Hi, HDF Experts,
H5Fcreate creates a new file named name in the *current directory.*
*How to create a HDF file in another directory?*
*How to specify a directory for a H5 file when calling H5Fopen?*
Thanks in advance for any help!

Just pass in a full path for the H5Fcreate’s ‘name’ parameter.

Normally, I would expect H5Fopen/creat calls to do same as thier posix equivalents.
I went looking through posix man pages for exactly how either open or creat form the 'path' of the file.
Surely, if you pass "foo.h5", it will create "foo.h5" in $CWD of the process.
And, as another respondent mentioned, if you pass a full path, it will create/open the file at that full path.
But, what if you pass "../bar/foo.h5"? will posix create the file in a dir named 'bar' that is one level up from $CWD? I don't know and I couldn't find refs on the system I was on that actually explain/define that behavior?
I think for anything other than a file in $CWD, might need to write a tiny bit of code that takes whatever path you are starting with and then uses get_cwd() and 'joins' the path you are given to form an absolute path to actually open.
HTH.
