socket_from_name(3ncs) [ultrix man page]
socket_from_name(3ncs) socket_from_name(3ncs) Name socket_from_name - convert a name and port number to a socket address Syntax #include <idl/c/socket.h> void socket_$from_name(family, name, nlength, port, sockaddr, slength, status) unsigned long family; socket_$string_t name; unsigned long nlength; unsigned long port; socket_$addr_t *sockaddr; unsigned long *slength; status_$t *status; Arguments family The integer representation of an address family. Value can be socket_$internet or socket_$unspec If the family parameter is socket_$unspec, then the name parameter is scanned for a prefix of family: (for example, ip:). name A string in the format family:host[port], where family:, host, and [port] are all optional. The family is an address family. The only valid family is ip. If you specify a family as part of the name parameter, you must specify socket_$unspec in the family parameter. The host is a host name. A leading number sign (#) can be used to indicate that the host name is in the standard numeric form (for example, #192.9.8.7). If host is omitted, the local host name is used. The port is a port number. If you spec- ify a port as part of the name parameter, the port parameter is ignored. nlength The length, in bytes, of name. port A port number. If you specify a port number in the name parameter, this parameter is ignored. sockaddr A socket address. slength The length, in bytes, of sockaddr. status The completion status. If the completion status returned in is equal to status_$ok , then the routine that supplied it was success- ful. Description The routine converts a textual address family, host name, and port number to a socket address. The address family and the port number can be either specified as separate parameters or included in the name parameter.

rpc_name_to_sockaddr(3ncs) rpc_name_to_sockaddr(3ncs) Name rpc_name_to_sockaddr - convert a host name and port number to a socket address (client or server) Syntax #include <idl/c/rpc.h> void rpc_$name_to_sockaddr(name, nlength, port, family, sockaddr, slength, status) unsigned char name; unsigned long nlength; unsigned long port; unsigned long family; socket_$addr_t *sockaddr; unsigned long *slength; status_$t *status; Arguments name A string that contains a host name and, optionally, a port and an address family. The format is family:host[port], where family: and [port] are optional. If you specify a family as part of the name parameter, you must specify socket_$unspec in the family parameter. The family part of the name parameter is ip; host is the host name; port is an integer port number. nlength The number of characters in name. port The socket port number. This parameter should have the value rpc_$unbound_port if you are not specifying a well-known port; in this case, the returned socket address will specify the Local Location Broker (LLB) forwarding port at host. If you specify the port number in the name parameter, this parameter is ignored. family The address family to use for the socket address. This value corresponds to the communications protocol used to access the socket and determines how the sockaddr is expressed. If you specify the address family in the name parameter, this parameter must have the value socket_$unspec. sockaddr The socket address corresponding to name, port, and family. slength The length, in bytes, of sockaddr. status The completion status. If the completion status returned in is equal to status_$ok , then the routine that supplied it was successful. Description The routine provides the socket address for a socket, given the host name, the port number, and the address family. You can specify the socket address information either as one text string in the name parameter or by passing each of the three elements as separate parameters( name, port, and family ); in the latter case, the name parameter should contain only the hostname. Diagnostics This section lists status codes for errors returned by this routine in rpc_$not_in_call An internal error. rpc_$proto_error An internal protocol error. This routine has been superseded by the routine. Files See Also intro(3ncs), rpc_sockaddr_to_name(3ncs), socket_from_name(3ncs) rpc_name_to_sockaddr(3ncs)
