Hello,

I just read on error handling and object discovery in HDF5. I came  
across H5Oexists\_by\_name and at first was surprised that it isn't  
available for Fortran. Then I found out it was added only recently in  
1.8.5. I guess that it hasn't been added because it isn't a high  
priority, or are there other reasons?

Best,  
Maik

PS: If there is no technical reason against it, then I'll look into  
creating patch.
