[mpich-discuss] difference between ADIOI_xxx_ReadDone and ADIOI_xxx_ReadComplete

Hi, I'm trying to implement an ADIO backend and I'd like to know what is the difference between ADIOI_xxx_ReadDone and ADIOI_xxx_ReadComplete (and respectively for Write)? When are these functions called? (I'm working with mpich 3.0.4) More generally is there somewhere a documentation explaining when and how each of the ADIOI_ functions are called? Thank you, Matthieu Dorier PhD student at ENS Cachan Brittany and IRISA http://people.irisa.fr/Matthieu.Dorier
