Field Documentation

icp_data

void* icp_data

The private data for a computation. A computation can save its current state before passing control to calling fom. It's a responsibility of the computation to manage the memory associated with icp_data.

icp_fom

struct m0_fom* icp_fom

The fom associated with the instance of a computation. A computation can register a fom callback on some channel, when it's going to return M0_FSO_WAIT. A typical use-case can be of a computation returning M0_FSO_WAIT to a calling fom, while waiting for disk or network i/o. In this case the associated fom is made to wait on a channel, internal to a computation, and it re-launches the computation when i/o completion is signalled.
