The members of this structure are:
getrpcent reads the next line of the file, opening the file if necessary.
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 beginning of the file until a matching rpc program name or program number is found, or until EOF is encountered.
