/* official name of service */ - char **s_aliases; /* alias list */ - int s_port; /* port service resides at */ - char *s_proto; /* protocol to use */ -}; -.Ed -.Pp -The members of this structure are: -.Bl -tag -width s_aliases -.It Fa s_name -The official name of the service. -.It Fa s_aliases -A null-terminated list of alternate names for the service. -.It Fa s_port -The port number at which the service resides. -Port numbers are returned in network byte order. -.It Fa s_proto -The name of the protocol to use when contacting the service. -.El -.Pp -The -.Fn getservent -function reads the next line of the file, opening the file if necessary. -.Pp -The -.Fn setservent -function opens and rewinds the file. -If the -.Fa stayopen -flag is non-zero, -the services database will not be closed after each call to -.Fn getservbyname -or -.Fn getservbyport . -.Pp -The -.Fn endservent -function closes the file. -.Pp -The -.Fn getservbyname -and -.Fn getservbyport -functions sequentially search from the beginning of the file until a -matching protocol name or port number (specified in network byte order) -is found, or until -.Dv EOF -is encountered. -If a protocol name is also supplied (non-null), -searches must also match the protocol. -.Pp -The -.Fn getservent_r , -.Fn getservbyport_r , -.Fn getservbyname_r , -.Fn setservent_r , -and -.Fn endservent_r -functions are reentrant versions of the above functions that take a -pointer to a -.Fa servent_data -structure which is used to store state information. -The structure must be zero-filled before it is used -and should be considered opaque for the sake of portability. -.Pp -The -.Fn getservent_r , -.Fn getservbyport_r , -and -.Fn getservbyname_r -functions -also take a pointer to a -.Fa servent -structure which is used to store the results of the database lookup. -.Sh RETURN VALUES -The -.Fn getservent , -.Fn getservbyport , -and -.Fn getservbyname -functions return a pointer to a -.Fa servent -structure on success or a null pointer if end-of-file -is reached or an error occurs. -.Pp -The -.Fn getservent_r , -.Fn getservbyport_r , -and -.Fn getservbyname_r -functions return 0 on success or \-1 if end-of-file -is reached or an error occurs. -.Sh FILES -.Bl -tag -width /etc/services -compact -.It Pa /etc/services -.El -.Sh SEE ALSO -.Xr getprotoent 3 , -.Xr services 5 -.Sh STANDARDS -The -.Fn getservent , -.Fn getservbynumber , -.Fn getservbyname , -.Fn setservent , -and -.Fn endservent -functions conform to -.St -p1003.1-2004 . -.Pp -The -.Fn getservent_r , -.Fn getservbyport_r , -.Fn getservbyname_r , -.Fn setservent_r , -and -.Fn endservent_r -functions are not currently standardized. -This implementation follows the API used by HP, IBM, and Digital. -.Sh HISTORY -The -.Fn getservent , -.Fn getservbyport , -.Fn getservbyname , -.Fn setservent , -and -.Fn endservent -functions appeared in -.Bx 4.2 . -.Pp -The -.Fn getservent_r , -.Fn getservbyport_r , -.Fn getservbyname_r , -.Fn setservent_r , -and -.Fn endservent_r -functions appeared in -.Ox 3.7 . -.Sh BUGS -The non-reentrant functions use static data storage; if the data is needed -for future use, it should be copied before any subsequent calls overwrite it. -Expecting port numbers to fit in a 32-bit quantity is probably naive. -- cgit v1.2.3-55-g6feb
