<html> <body> <pre> NAME getservent, getservbyname, getservbyport - get service entry SYNOPSIS #include <network.h> struct servent *getservbyname(const char *name, const char *proto); struct servent *getservbyport(int port, const char *proto); DESCRIPTION The getservbyname() function returns a servent structure for the line from /etc/services that matches the service name using protocol proto. The getservbyport() function returns a servent structure for the line that matches the port port given in network byte order using protocol proto. The servent structure is defined in <netdb.h> as follows: struct servent { char *s_name; /* official service name */ char **s_aliases; /* alias list */ int s_port; /* port number */ char *s_proto; /* protocol to use */ } The members of the servent structure are: s_name The official name of the service. s_aliases A zero terminated list of alternative names for the service. s_port The port number for the service given in network byte order. s_proto The name of the protocol to use with this service. RETURN VALUE The getservbyname() and getservbyport() functions return the servent structure, or a NULL pointer if an error occurs. </pre> </body> </html>
