The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
rpc_remove_pipe_dir_object – remove a rpc_pipe_dir_object from a directory Synopsis void rpc_remove_pipe_dir_object(struct net *net, struct rpc_pipe_dir_head *pdh, struct rpc_pipe_dir_object *pdo); Arguments net pointer to struct net pdh pointer to struct rpc_pipe_dir_head pdo pointer to struct rpc_pipe_dir_object Copyright
rpc_queue_upcall – queue an upcall message to userspace Synopsis int rpc_queue_upcall(struct rpc_pipe *pipe, struct rpc_pipe_msg *msg); Arguments pipe upcall pipe on which to queue given message msg message to queue Description Call with an inode created by rpc_mkpipe to queue an upcall. A userspace process may then later read the upcall by performing a read…
rpc_protocol – Get transport protocol number for an RPC client Synopsis int rpc_protocol(struct rpc_clnt *clnt); Arguments clnt RPC client to query Copyright
rpc_peeraddr2str – return remote peer address in printable format Synopsis const char *rpc_peeraddr2str(struct rpc_clnt *clnt, enum rpc_display_format_t format); Arguments clnt RPC client structure format address format Description NB: the lifetime of the memory referenced by the returned pointer is the same as the rpc_xprt itself. As long as the caller uses this pointer, it must…
rpc_peeraddr – extract remote peer address from clnt’s xprt Synopsis size_t rpc_peeraddr(struct rpc_clnt *clnt, struct sockaddr *buf, size_t bufsize); Arguments clnt RPC client structure buf target buffer bufsize length of target buffer Description Returns the number of bytes that are actually in the stored address. Copyright
rpc_net_ns – Get the network namespace for this RPC client Synopsis struct net *rpc_net_ns(struct rpc_clnt *clnt); Arguments clnt RPC client to query Copyright
rpc_mkpipe_dentry – make an rpc_pipefs file for kernel<->userspace communication Synopsis struct dentry *rpc_mkpipe_dentry(struct dentry *parent, const char *name, void *private, struct rpc_pipe *pipe); Arguments parent dentry of directory to create new “pipe” in name name of pipe private private data to associate with the pipe, for the caller’s use pipe rpc_pipe containing input parameters Description…
rpc_max_payload – Get maximum payload size for a transport, in bytes Synopsis size_t rpc_max_payload(struct rpc_clnt *clnt); Arguments clnt RPC client to query Description For stream transports, this is one RPC record fragment (see RFC 1831), as we don’t support multi-record requests yet. For datagram transports, this is the size of an IP packet minus the…
rpc_max_bc_payload – Get maximum backchannel payload size, in bytes Synopsis size_t rpc_max_bc_payload(struct rpc_clnt *clnt); Arguments clnt RPC client to query Copyright
rpc_malloc – allocate RPC buffer resources Synopsis int rpc_malloc(struct rpc_task *task); Arguments task RPC task Description A single memory region is allocated, which is split between the RPC call and RPC reply that this task is being used for. When this RPC is retired, the memory is released by calling rpc_free. To prevent rpciod from…
rpc_localaddr – discover local endpoint address for an RPC client Synopsis int rpc_localaddr(struct rpc_clnt *clnt, struct sockaddr *buf, size_t buflen); Arguments clnt RPC client structure buf target buffer buflen size of target buffer, in bytes Description Returns zero and fills in “buf” and “buflen” if successful; otherwise, a negative errno is returned. This works even…
