Enumeration Type Documentation

enum p9_proto_versions

enum p9_proto_versions - 9P protocol versions : 9P Legacy mode, pre-9P2000.u : 9P2000.u extension : 9P2000.L extension

Enumerator:

p9_proto_legacy
p9_proto_2000u
p9_proto_2000L

Definition at line 38 of file client.h.

enum p9_req_status_t

enum p9_req_status_t - status of a request : request slot unused : request has been allocated but not sent : request waiting to be sent : request sent to server : a flush has been sent for this request : response received from server : request has been flushed : request encountered an error on the client side

The state is used to mark a request slot as unused but use is actually tracked by the idpool structure which handles tag id allocation.

Enumerator:

REQ_STATUS_IDLE
REQ_STATUS_ALLOC
REQ_STATUS_UNSENT
REQ_STATUS_SENT
REQ_STATUS_FLSH
REQ_STATUS_RCVD
REQ_STATUS_FLSHD
REQ_STATUS_ERROR

Definition at line 79 of file client.h.

enum p9_trans_status

enum p9_trans_status - different states of underlying transports : transport is connected and healthy : transport has been disconnected : transport is connected by wedged

This enumeration details the various states a transport instatiation can be in.

Enumerator:

Connected
BeginDisconnect
Disconnected
Hung
