[mpich-discuss] difference between ADIOI_xxx_ReadDone and ADIOI_xxx_ReadComplete

[Matthieu Dorier]

Thanks Rajeev!

>From reading further the code, I understand that the ReadDone function is called automatically after a read is finished (a sort of callback, somehow?) while the Complete function would be called when the user waits on a request corresponding to an asynchronous I/O operation. Am I correct?
