#define | SOCKET unsigned int |
In Win32, sockets use unsigned integers; in UNIX, they use signed integer. | |
#define | SOCK_ASSERT(msg, expr) { fprintf(stderr, "%s\n", msg); assert(expr); } |
DEBUG facility: it prints an error message on the screen (stderr). | |
#define | SOCKBUF_CHECKONLY 1 |
'checkonly' flag, into the rpsock_bufferize() | |
#define | SOCKBUF_BUFFERIZE 0 |
no 'checkonly' flag, into the rpsock_bufferize() | |
#define | SOCKOPEN_CLIENT 0 |
no 'server' flag; it opens a client socket | |
#define | SOCKOPEN_SERVER 1 |
'server' flag; it opens a server socket | |
#define | SOCK_RECEIVEALL_NO 0 |
Changes the behaviour of the sock_recv(); it does not wait to receive all data. | |
#define | SOCK_RECEIVEALL_YES 1 |
Changes the behaviour of the sock_recv(); it waits to receive all data. | |
Functions | |
int | sock_init (char *errbuf, int errbuflen) |
It initializes sockets. | |
void | sock_cleanup () |
It deallocates sockets. | |
void | sock_geterror (const char *caller, char *errbuf, int errbufsize) |
It retrieves the error message after an error occurred in the socket interface. | |
int | sock_initaddress (const char *address, const char *port, struct addrinfo *hints, struct addrinfo **addrinfo, char *errbuf, int errbuflen) |
Checks that the address, port and flags given are valids and it returns an 'addrinfo' stucture. | |
int | sock_recv (SOCKET socket, char *buffer, int size, int receiveall, char *errbuf, int errbuflen) |
It waits on a connected socket and it manages to receive data. | |
SOCKET | sock_open (struct addrinfo *addrinfo, int server, int nconn, char *errbuf, int errbuflen) |
It initializes a network connection both from the client and the server side. | |
int | sock_close (SOCKET sock, char *errbuf, int errbuflen) |
Closes the present (TCP and UDP) socket connection. | |
int | sock_send (SOCKET socket, const char *buffer, int size, char *errbuf, int errbuflen) |
It sends the amount of data contained into 'buffer' on the given socket. | |
int | sock_bufferize (const char *buffer, int size, char *tempbuf, int *offset, int totsize, int checkonly, char *errbuf, int errbuflen) |
It copies the amount of data contained into 'buffer' into 'tempbuf'. and it checks for buffer overflows. | |
int | sock_discard (SOCKET socket, int size, char *errbuf, int errbuflen) |
It waits on a connected socket and it manages to receive one message. It discards N bytes that are currently waiting to be read on the current socket. | |
int | sock_check_hostlist (char *hostlist, const char *sep, struct sockaddr_storage *from, char *errbuf, int errbuflen) |
Checks that one host (identified by the sockaddr_storage structure) belongs to an 'allowed list'. | |
int | sock_cmpaddr (struct sockaddr_storage *first, struct sockaddr_storage *second) |
Compares two addresses contained into two sockaddr_storage structures. | |
int | sock_getascii_addrport (const struct sockaddr_storage *sockaddr, char *address, int addrlen, char *port, int portlen, int flags, char *errbuf, int errbuflen) |
It retrieves two strings containing the address and the port of a given 'sockaddr' variable. | |
int | sock_present2network (const char *address, struct sockaddr_storage *sockaddr, char *errbuf, int errbuflen) |
It translates an address from the 'presentation' form into the 'network' form. |
