Detailed Description

Fop state machine for Spiel operations

See also: fom

FOP state machines for various Spiel operation

Note: Naming convention: For operation xyz, the FOP is named as m0_fop_xyz, its corresponding reply FOP is named as m0_fop_xyz_rep and FOM is named as m0_fom_xyz. For each FOM type, its corresponding create, state and fini methods are named as m0_fom_xyz_create, m0_fom_xyz_state, m0_fom_xyz_fini respectively.
