getrpcent, getrpcbyname, getrpcbynumber, endrpcent, setrpcent -- get RPC entry
Standard C Library (libc, -lc)
#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);
getrpcent(), getrpcbyname(), and getrpcbynumber(), 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 alternative names for the rpc program. r_number The rpc program number for this service. getrpcent() reads the next line of the file, opening the file if neces- sary. setrpcent() 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). endrpcent() closes the file. getrpcbyname() and getrpcbynumber() sequentially search from the begin- ning of the file until a matching rpc program name or program number is found, or until end-of-file is encountered.
A NULL pointer is returned on EOF or error.
