Functions

int net_connect (int *fd, char *host, int port)

Initiate a TCP connection with host:port.

int net_bind (int *fd, char *bind_ip, int port)

Create a listening socket on bind_ip:port. If bind_ip == NULL, all interfaces are binded.

int net_accept (int bind_fd, int *client_fd, void *client_ip)

Accept a connection from a remote client.

int net_set_block (int fd)

Set the socket blocking.

int net_set_nonblock (int fd)

Set the socket non-blocking.

void net_usleep (unsigned long usec)

Portable usleep helper.

int net_recv (void *ctx, unsigned char *buf, int len)

Read at most 'len' characters. len is updated to reflect the actual number of characters read.

int net_send (void *ctx, unsigned char *buf, int len)

Write at most 'len' characters. len is updated to reflect the number of characters _not_ written.

void net_close (int fd)

Gracefully shutdown the connection.

Function Documentation

int net_accept ( int bind_fd,

int * client_fd,

void * client_ip

)

Accept a connection from a remote client.

Returns:: 0 if successful, XYSSL_ERR_NET_ACCEPT_FAILED, or XYSSL_ERR_NET_WOULD_BLOCK is bind_fd was set to non-blocking and accept() is blocking.

Referenced by main(), and ssl_test().

int net_bind ( int * fd,

char * bind_ip,

int port

)

Create a listening socket on bind_ip:port. If bind_ip == NULL, all interfaces are binded.

Returns:: 0 if successful, or one of: XYSSL_ERR_NET_SOCKET_FAILED, XYSSL_ERR_NET_BIND_FAILED, XYSSL_ERR_NET_LISTEN_FAILED

Referenced by main(), and ssl_test().

void net_close ( int fd )

Gracefully shutdown the connection.

Referenced by main(), and ssl_test().

int net_connect ( int * fd,

char * host,

int port

)

Initiate a TCP connection with host:port.

Returns:: 0 if successful, or one of: XYSSL_ERR_NET_SOCKET_FAILED, XYSSL_ERR_NET_UNKNOWN_HOST, XYSSL_ERR_NET_CONNECT_FAILED

Referenced by main(), and ssl_test().

int net_recv ( void * ctx,

unsigned char * buf,

int len

)

Read at most 'len' characters. len is updated to reflect the actual number of characters read.

Returns:: This function returns the number of bytes received, or a negative error code; XYSSL_ERR_NET_TRY_AGAIN indicates read() is blocking.

Referenced by main(), and ssl_test().

int net_send ( void * ctx,

unsigned char * buf,

int len

)

Write at most 'len' characters. len is updated to reflect the number of characters _not_ written.

Returns:: This function returns the number of bytes sent, or a negative error code; XYSSL_ERR_NET_TRY_AGAIN indicates write() is blocking.

Referenced by main(), and ssl_test().

int net_set_block ( int fd )

Set the socket blocking.

Returns:: 0 if successful, or a non-zero error code

int net_set_nonblock ( int fd )

Set the socket non-blocking.

Returns:: 0 if successful, or a non-zero error code

Referenced by ssl_test().

void net_usleep ( unsigned long usec )

Portable usleep helper.

Note:: Real amount of time slept will not be less than select()'s timeout granularity (typically, 10ms).
