* This function is used with connection-based socket types

* returns a new file descriptor referring to that socket.
|
|
* The newly created socket is not in the listening state.
|
|
* The original socket sd is unaffected by this call.
|
|
* The argument sd is a socket that has been created with socket(),
|
|
* bound to a local address with bind(), and is listening for
|
|
* connections after a listen(). The argument addr is a pointer
|
|
* to a sockaddr structure. This structure is filled in with the
|
|
* address of the peer socket, as known to the communications layer.
|
|
* The exact format of the address returned addr is determined by the

* socket's address family. The addrlen argument is a value-result

|
* argument: it should initially contain the size of the structure
|
|
* pointed to by addr, on return it will contain the actual
|
|
* length (in bytes) of the address returned.

* Options may exist at multiple protocol levels; they are always

|
|
* When manipulating socket options the level at which the option

* resides and the name of the option must be specified.

* To manipulate options at the socket level, level is specified as
|
|
* SOL_SOCKET. To manipulate options at any other level the protocol
|
|
* number of the appropriate protocol controlling the option is
|
|
* supplied. For example, to indicate that an option is to be
|
|
* interpreted by the TCP protocol, level should be set to the
|
|
* protocol number of TCP;
|
|
* The parameters value and value_len are used to access value -
|
|
* use for setsockopt(). For getsockopt() they identify a buffer
|
|
* in which the value for the requested option(s) are to

* be returned. For getsockopt(), value_len is a value-result
|
|
* parameter, initially containing the size of the buffer

|
* pointed to by option_value, and modified on return to
|
|
* indicate the actual size of the value returned. If no option
|
|
* value is to be supplied or returned, option_value may be NULL.
|
|
*
|
|
* NOTE: On this version the following two socket options are enabled:
|
|
* The only protocol level supported in this version
|
|
* is SOL_SOCKET (level).
|
|
*
|
|
* 1. SOCKOPT_RECV_TIMEOUT (option)
|
|
* SOCKOPT_RECV_TIMEOUT configures recv and recvfrom timeout
|
|
* in milliseconds. In that case value should be pointer to

|
* unsigned long.
|
|
* 2. SOCKOPT_NONBLOCK (option). sets the socket non-blocking mode on

* or off. In that case value should be SOCK_ON or SOCK_OFF (value).
|
|
*
|
|
* Input Parameters:
|
|
* sockfd socket handle
|
|
* level defines the protocol level for this option
|

* option defines the option name to Interrogate

* resides and the name of the option must be specified.
|
|
* To manipulate options at the socket level, level is specified as
|
|
* SOL_SOCKET. To manipulate options at any other level the protocol
|
|
* number of the appropriate protocol controlling the option is
|
|
* supplied. For example, to indicate that an option is to be
|
|
* interpreted by the TCP protocol, level should be set to the
|
|
* protocol number of TCP;
|
|
* The parameters value and value_len are used to access value -
|
|
* use for setsockopt(). For getsockopt() they identify a buffer
|
|
* in which the value for the requested option(s) are to
|
|
* be returned. For getsockopt(), value_len is a value-result
|
|
* parameter, initially containing the size of the buffer
|
|
* pointed to by option_value, and modified on return to
|
|
* indicate the actual size of the value returned. If no option
|
|
* value is to be supplied or returned, option_value may be NULL.
|
|
*
|
|
* NOTE: On this version the following two socket options are enabled:
|
|
* The only protocol level supported in this version
|
|
* is SOL_SOCKET (level).
|
|
* 1. SOCKOPT_RECV_TIMEOUT (option)
|
|
* SOCKOPT_RECV_TIMEOUT configures recv and recvfrom timeout
|
|
* in milliseconds.
|
|
* In that case value should be pointer to unsigned long.
|
|
* 2. SOCKOPT_NONBLOCK (option). sets the socket non-blocking mode on
|
|
* or off.
|
|
* In that case value should be SOCK_ON or SOCK_OFF (value).
|
|
*
|
|
* Input Parameters:
|
|
* sockfd socket handle
|
|
* level defines the protocol level for this option
|
|
* option defines the option name to Interrogate
|
|
* value specifies a value for the option
|
|
* value_len specifies the length of the option value
|
|
*
|
|
* Returned Value:
|
|
* On success, zero is returned. On error, -1 is returned
