Member Function Documentation
| virtual SocketInterface* allocateSocket | ( | socket_protocol_t | socketProtocol ) | [pure virtual] |
Allocate space for a socket.
- Parameters:
-
The type of socket you want to open, SOCK_TCP or SOCK_UDP
- Returns:
- a pointer to the allocated socket.
| virtual int32_t connect | ( | uint32_t | timeout_ms = 15000 ) |
[pure virtual] |
Start the interface, using DHCP if needed.
- Parameters:
-
timeout_ms Time in miliseconds to wait while attempting to connect before timing out
- Returns:
- 0 on success, a negative number on failure
| virtual int deallocateSocket | ( | SocketInterface * | socket ) | [pure virtual] |
Deallocate space for a socket.
- Parameters:
-
An allocated SocketInterface
- Returns:
- 0 if object is destroyed, -1 otherwise
| virtual int32_t disconnect | ( | void | ) | [pure virtual] |
Stop the interface, bringing down dhcp if necessary.
- Returns:
- 0 on success, a negative number on failure
| virtual char* getGateway | ( | void | ) | const [pure virtual] |
Get the current gateway address.
- Returns:
- a pointer to a string containing the gateway address.
| virtual char* getIPAddress | ( | void | ) | [pure virtual] |
Get the current IP address.
- Returns:
- a pointer to a string containing the IP address.
| virtual char* getMACAddress | ( | void | ) | const [pure virtual] |
Get the devices MAC address.
- Returns:
- a pointer to a string containing the mac address.
| virtual char* getNetworkMask | ( | void | ) | const [pure virtual] |
Get the current network mask.
- Returns:
- a pointer to a string containing the network mask.
| virtual int32_t init | ( | const char * | ip, |
| const char * | mask, | ||
| const char * | gateway | ||
| ) | [pure virtual] |
Initialize the network interface with a static IP address.
- Parameters:
-
ip The static IP address to use mask The IP address mask gateway The gateway to use
- Returns:
- 0 on success, a negative number on failure
| virtual int32_t init | ( | void | ) | [pure virtual] |
Initialize the network interface with DHCP.
- Returns:
- 0 on success, a negative number on failure
| virtual int32_t isConnected | ( | void | ) | [pure virtual] |
Get the current status of the interface connection.
- Returns:
- true if connected, a negative number on failure
