Detailed Description

9P Protocol.

The sys/9p.h header provides definitions for the 9P protocol, a distributed file system protocol developed by Bell Labs.

Messages

Message types prefixed with 'T' are client-to-server messages, while those prefixed with 'R' are server-to-client messages and are usually in response to a 'T' message. The client is the entity initiating requests, and the server is the entity responding to those requests.

All messages follow the format size[4] type[1] tag[2] ... where size is the total size of the message in bytes (including the size field itself), type is one of the message types defined in ninep_msg_type_t, and tag is a identifier used to match requests and responses.

Note

The values specified within square brackets indicate the size of each field in bytes and all multi-byte fields are encoded in little-endian format.
