The members of this structure are:
Getprotoent reads the next line of the file, opening the file if necessary.
Setprotoent opens and rewinds the file. If the stayopen flag is non-zero, the net data base will not be closed after each call to getprotobyname or getprotobynumber.
Endprotoent closes the file.
Getprotobyname and getprotobynumber sequentially search from the beginning of the file until a matching protocol name or protocol number is found, or until EOF is encountered.
