Nsysnet.rpl

nsysnet.rpl is the library that provides BSD socket related functions.

Functions

Base

Name	Prototype	Description	Returns
SOInit	int SOInit(void);	Initializes the library.	SO_*
SOFinish	int SOFinish(void);	Cleans up after the library.	SO_*

Networking

These are also available under their standard BSD names (connect(), recv(), send(), etc.), without the SO_* prefix.

Name	Prototype	Description	Returns
SOConnect	int SOConnect(int fd, struct sockaddr *addr, int addrlen);	Connects to the defined target	SO_*
SOListen	int SOListen(int fd, int backlog);	Listens for connections	SO_*
SORecv	int SORecv(int fd, void *buffer, int len, int flags);	Receive data from a remote socket	SO_*
SORecvFrom	int SORecvFrom(int fd, void *buffer, int len, int flags, struct sockaddr *from, int *fromlen);	Same as SORecv but with target specified	SO_*
SOSend	int SOSend(int fd, const void *buffer, int len, int flags);	Send data to remote socket	SO_*
SOSendTo	int SOSendTo(int fd, const void *buffer, int len, int flags, const struct sockaddr *dest_addr, int dest_len);	Same as SOSend but with target specified	SO_*

Error

Name	Prototype	Description	Returns
SOInit	int SOLastError(void);	Recives the latest error???	The latest error(SO_*)???

Error Codes

The error codes that SO functions can return. if the error code starts with "SO_E" so were the operation not successful otherwise it were.

Name	Value	Description
SO_SUCCESS	0	The operation were successful
SO_ETIMEDOUT	2	The connection timed out
SO_ECONNREFUSED	7	The connection were refused
SO_ERROR	41	The operation hit a generic error and were not successful
SO_ELIBNOTREADY	43	The library is not ready, did you forget to initialize it?

Structures

Name	Data
sockaddr_in	typedef struct { u16 sin_family; u16 sin_port; struct in_addr sin_addr; char sin_zero[8]; } sockaddr_in;
