| INITIALIZE |
Use the INITIALIZE command
to preallocate a socket set. |
| SOCKETSET |
Use the SOCKETSET command
to retrieve the name of the active socket set. If you specify the
name of a socket set as a parameter, then that socket set becomes
the active socket set. |
| SOCKETSETLIST |
Use the SOCKETSETLIST
command to list the names of all available socket sets that are currently
defined by the application. |
| SOCKETSETSTATUS |
Use the SOCKETSETSTATUS
command to list information about a socket set. |
| TERMINATE |
Use the TERMINATE command
to close all sockets in the specified socket set and to release the
socket set. |
| Commands to open, close, and
manipulate sockets |
| ACCEPT |
Use the ACCEPT command to accept
new connections from a client. |
| BIND |
Use the BIND command to bind a
local NAME string to a socket descriptor. |
| BIND2ADDRSEL |
Use the BIND2ADDRSEL command
to bind a socket to the local IP address that would be selected by
the stack to communicate with the input destination IP address. |
| CLOSE |
Use the CLOSE command to close
a socket and release the resources that are associated with the socket
descriptor. |
| CONNECT |
A client application uses the
CONNECT command to establish a connection between a local socket and
a remote socket. |
| GIVESOCKET |
Use the GIVESOCKET command
to transfer a socket descriptor to another application that is running
on the same host. |
| LISTEN |
Use the LISTEN command to determine
whether a socket is ready to accept client connection requests. |
| SHUTDOWN |
Use the SHUTDOWN command to
shut down all or part of a duplex connection. |
| SOCKET |
Use the SOCKET command to open
a socket descriptor in the active socket set. |
| TAKESOCKET |
Use the TAKESOCKET command
to take a socket descriptor that is passed from another program using
the GIVESOCKET command. A socket descriptor can be taken by an application
only when the socket is in the same address family. |
| Commands to exchange data on
sockets |
| READ |
Use the READ command to read data
on the specified socket. The maximum amount of data to be read is
specified by the maxlength parameter. If the socket
is in blocking mode and data is not available on the socket, the command
blocks until data arrives. |
| RECV |
Use the RECV command to receive
data on a specified socket. The RECV command can be issued only against
connected sockets. |
| RECVFROM |
Use the RECVFROM command to
receive data on the specified socket. |
| SEND |
Use the SEND command to send an
outgoing message on the connected socket. |
| SENDTO |
Use the SENDTO command to send
an outgoing message on a socket descriptor. This command differs from
the SEND command in that it includes the destination address as a
parameter. |
| WRITE |
Use the WRITE command to send an outgoing
message on the connected socket. The WRITE command is similar to the SEND
command, except that the WRITE command does not support the control flags
that are available with the SEND command. |
| Commands to resolve host names
and IP addresses |
| GETADDRINFO |
Use the GETADDRINFO command
to resolve host or service name information. |
| GETCLIENTID |
Use the GETCLIENTID command
to retrieve the client ID for the calling application. The client
ID is the identifier by which the calling application is known to
the TCP/IP address space. |
| GETDOMAINNAME |
Use the GETDOMAINNAME
command to retrieve the name of the domain to which the current TCP/IP
stack belongs. |
| GETHOSTBYADDR |
Use the GETHOSTBYADDR
command to resolve an IPv4 address to a host name. |
| GETHOSTBYNAME |
Use the GETHOSTBYNAME
command to resolve a host name to an IPv4 address. |
| GETHOSTID |
Use the GETHOSTID command
to return the primary IPv4 address for the current host. The primary
address is the IP address of the default home address that is specified
in the TCP/IP configuration file for the stack with which the current
socket set is associated. |
| GETHOSTNAME |
Use the GETHOSTNAME command
to return the name of the host on which the application is running |
| GETNAMEINFO |
Use the GETNAMEINFO command
to translate a socket address to a node name and service location. |
| GETPEERNAME |
Use the GETPEERNAME command
to return the name of the remote peer that is connected to the socket. |
| GETPROTOBYNAME |
Use the GETPROTOBYNAME
command to translate a network protocol name to a protocol number. |
| GETPROTOBYNUMBER |
Use the GETPROTOBYNUMBER command
to translate a network protocol number to a protocol name. |
| GETSERVBYNAME |
Use the GETSERVBYNAME
command to retrieve a service and port number. |
| GETSERVBYPORT |
Use the GETSERVBYPORT
command to translate a port number to the name of the service that
is using the port. |
| GETSOCKNAME |
Use the GETSOCKNAME command
to retrieve the name of a bound socket. |
| INET6ISSRCADDR |
Use the INET6ISSRCADDR
command to indicate whether an input IPV6 socket address matches an
address that is defined to the stack, which conforms to one or more
input IPV6_ADDR_PREFERENCES flags. |
| RESOLVE |
Use the RESOLVE command to resolve
a host name or an IP address. |
| Commands to manage socket configuration,
options, and modes |
| FCNTL |
Use the FCNTL command to control
the operating characteristics of a socket. |
| GETSOCKOPT |
Use the GETSOCKOPT command
to retrieve the active socket options that were set by the SETSOCKOPT
command. |
| IOCTL |
Use the IOCTL command to perform
control functions on sockets. |
| SELECT |
Use the SELECT command to monitor
groups of sockets to determine when one or more of the sockets is
ready for a read operation, is ready for a write operation, or has
an exception pending. |
| SETSOCKOPT |
Use the SETSOCKOPT command
to set socket options. |
| VERSION |
Use the VERSION command to retrieve
the name, version number, and version date of the REXX socket library. |
