#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 |
#define | SOCKBUF_BUFFERIZE 0 |
#define | SOCKOPEN_CLIENT 0 |
#define | SOCKOPEN_SERVER 1 |
#define | SOCK_ERRBUF_SIZE 256 |
Functions | |
void | sock_geterror (const char *caller, char *string, int size) |
It retrieves the error message after an error occurred in the socket interface. | |
int | sock_init (char *errbuf) |
It initializes sockets. | |
void | sock_cleanup () |
It deallocates sockets. | |
int | sock_validaddr (const char *address, const char *port, struct addrinfo *hints, struct addrinfo **addrinfo, char *errbuf) |
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, char *errbuf) |
It waits on a connected socket and it manages to receive exactly 'size' bytes. | |
int | sock_recv_dgram (SOCKET sock, char *buffer, int size, char *errbuf) |
It waits on a connected socket and it manages to receive one message. | |
int | sock_open (struct addrinfo *addrinfo, int server, int nconn, char *errbuf) |
It initializes a network connection both from the client and the server side. | |
int | sock_close (SOCKET sock, char *errbuf) |
Closes the present (TCP and UDP) socket connection. | |
int | sock_send (SOCKET socket, const char *buffer, int size, char *errbuf) |
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) |
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) |
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) |
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. |
