These routines are associated with the server side of the RPC
mechanism. Some of them are called by the server side dispatch function,
while others (such as svc_run
()) are called when the
server is initiated.
SVCXPRT
data structure.
svc_dg_enablecache
()svc_exit
()svc_run
() to return.
As currently implemented, svc_exit
()
zeroes the svc_fdset
global variable. If RPC
server activity is to be resumed, services must be reregistered with the
RPC library either through one of the
rpc_svc_create
() functions, or using
xprt_register
().
svc_exit
() has global scope and ends all RPC
server activity. fd_set svc_fdset A global
variable reflecting the RPC server's read file descriptor bit mask; it
is suitable as a parameter to the
select(2) system call.
This is only of interest if service implementors do not call
svc_run
(), but rather do their own asynchronous
event processing. This variable is read-only (do not pass its address to
select(2)!), yet it may
change after calls to svc_getreqset
() or any
creation routines.
svc_freeargs
()svc_getargs
(). This routine returns
TRUE
if the results were successfully freed, and
FALSE
otherwise.svc_getargs
()TRUE
if
decoding succeeds, and FALSE
otherwise.svc_getreq_common
()svc_getreq_poll
()svc_run
(), but instead implements custom
asynchronous event processing. It is called when
poll(2) has determined that an
RPC request has arrived on some RPC file descriptors;
pollretval
() is the return value from
poll(2) and
pfdp is the array of pollfd
structures on which the
poll(2) was done. It is
assumed to be an array large enough to contain the maximal number of
descriptors allowed.svc_getreqset
()svc_run
(), but instead implements custom
asynchronous event processing. It is called when
poll(2) has determined that an
RPC request has arrived on some RPC file descriptors;
rdfds is the resultant read file descriptor bit
mask. The routine returns when all file descriptors associated with the
value of rdfds have been serviced.svc_getrpccaller

identifying the calling client. This only works if the client is calling
the server over an AF_LOCAL
socket.svc_run
(). Service implementors who do not call
svc_run
() and who wish to use this array must
perform this derivation themselves.svc_run

is usually waiting for the
