GETRPCENT(3) FreeBSD Library Functions Manual GETRPCENT(3)
NAME getrpcent, getrpcbyname, getrpcbynumber, endrpcent, setrpcent - get RPC entry
LIBRARY Standard C Library (libc, -lc)
SYNOPSIS #include <rpc/rpc.h>
struct rpcent * getrpcent(void);
struct rpcent * getrpcbyname(const char *name);
struct rpcent * getrpcbynumber(int number);
void setrpcent(int stayopen);
void endrpcent(void);
DESCRIPTION The getrpcent(), getrpcbyname(), and getrpcbynumber() functions each return a pointer to an object with the following structure containing the broken-out fields of a line in the rpc program number data base, /etc/rpc:
struct rpcent { char *r_name; /* name of server for this rpc program */ char **r_aliases; /* alias list */ long r_number; /* rpc program number */ };
The members of this structure are:
r_name The name of the server for this rpc program.
r_aliases A zero terminated list of alternate names for the rpc program.
r_number The rpc program number for this service.
The getrpcent() function reads the next line of the file, opening the file if necessary.
The setrpcent() function opens and rewinds the file. If the stayopen flag is non-zero, the net data base will not be closed after each call to getrpcent() (either directly, or indirectly through one of the other "getrpc" calls).
The endrpcent() function closes the file.
The getrpcbyname() and getrpcbynumber() functions sequentially search A NULL pointer is returned on EOF or error.
