SVC_XPRT_NAMES(9) Linux Networking SVC_XPRT_NAMES(9)NAME
svc_xprt_names - format a buffer with a list of transport names
SYNOPSIS
int svc_xprt_names(struct svc_serv * serv, char * buf, const int buflen);
ARGUMENTS
serv
pointer to an RPC service
buf
pointer to a buffer to be filled in
buflen
length of buffer to be filled in
DESCRIPTION
Fills in buf with a string containing a list of transport names, each name terminated with '
'.
Returns positive length of the filled-in string on success; otherwise a negative errno value is returned if an error occurs.

GETRPCENT_R(3) Linux Programmer's Manual GETRPCENT_R(3)NAME
getrpcent_r, getrpcbyname_r, getrpcbynumber_r - get RPC entry (reentrant)
SYNOPSIS
#include <netdb.h>
int getrpcent_r(struct rpcent *result_buf, char *buf,
size_t buflen, struct rpcent **result);
int getrpcbyname_r(const char *name,
struct rpcent *result_buf, char *buf,
size_t buflen, struct rpcent **result);
int getrpcbynumber_r(int number,
struct rpcent *result_buf, char *buf,
size_t buflen, struct rpcent **result);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
getrpcent_r(), getrpcbyname_r(), getrpcbynumber_r():
_BSD_SOURCE || _SVID_SOURCE
DESCRIPTION
The getrpcent_r(), getrpcbyname_r(), and getrpcbynumber_r() functions are the reentrant equivalents of, respectively, getrpcent(3), getr-
pcbyname(3), and getrpcbynumber(3). They differ in the way that the rpcent structure is returned, and in the function calling signature
and return value. This manual page describes just the differences from the nonreentrant functions.
Instead of returning a pointer to a statically allocated rpcent structure as the function result, these functions copy the structure into
the location pointed to by result_buf.
The buf array is used to store the string fields pointed to by the returned rpcent structure. (The nonreentrant functions allocate these
strings in static storage.) The size of this array is specified in buflen. If buf is too small, the call fails with the error ERANGE, and
the caller must try again with a larger buffer. (A buffer of length 1024 bytes should be sufficient for most applications.)
If the function call successfully obtains an RPC record, then *result is set pointing to result_buf; otherwise, *result is set to NULL.
RETURN VALUE
On success, these functions return 0. On error, they return one of the positive error numbers listed in ERRORS.
On error, record not found (getrpcbyname_r(), getrpcbynumber_r()), or end of input (getrpcent_r()) result is set to NULL.
ERRORS
ENOENT (getrpcent_r()) No more records in database.
ERANGE buf is too small. Try again with a larger buffer (and increased buflen).
CONFORMING TO
These functions are GNU extensions. Functions with similar names exist on some other systems, though typically with different calling sig-
natures.

I want to create a new user and grant him ONLY transfer files access to a specific directory where he can only upload and read the files. He should be restricted to this activity only.
