Function Documentation

int rd (  int  fd, char *  data, int *  len, int  maxlen )

Read a data segment from a network stream. This function will block until the specified length has been received. Parameters: fd  [in] file descriptor data  [out] buffer to store the read data len  [out] received length in bytes maxlen  [in] maximum length of data buffer in bytes Returns: received data length in bytes, or -1 on error. Definition at line 43 of file rdwt.c. Referenced by adin_tcpip_read().

int wt (  int  fd, char *  data, int  len )

Write a data segment to a network stream. Parameters: fd  [in] file descriptor data  [in] buffer that holds data to write len  [out] received length in bytes Returns: actually written data length in bytes, or -1 on error. Definition at line 92 of file rdwt.c. Referenced by adin_tcpip_send_pause(), adin_tcpip_send_resume(), and adin_tcpip_send_terminate().

int ready_as_server (  int  port_num  )

Prepare as a server creating a socket for client connection. Parameters: port_num  [in] network port to listen. Returns: socket descriptor, or -1 if failed to create socket, -2 if failed to bind, or -3 if failed to listen. Definition at line 40 of file server-client.c. Referenced by adin_tcpip_standby(), and main_module_loop().

int accept_from (  int  sd  )

Wait for a request from client. This function blocks until a connection request comes. Parameters: sd  [in] listening server socket descpritor Returns: the connected socket descriptor. Definition at line 116 of file server-client.c. Referenced by adin_tcpip_begin().

int make_connection (  char *  hostname, int  port_num )

Make a connection to a server. Parameters: hostname  [in] server host (host name or numeric IP address) port_num  [in] port number Returns: new socket descriptor, -1 if fails to prepare socket, -2 if fails to connect, -3 if host name is wrong. Definition at line 161 of file server-client.c.

int make_connection_unix (  char *  address  )

Make a connection to a server using unix domain socket. Parameters: address  [in] unix domain socket address (path) Returns: new socket descriptor, -1 if fails to prepare socket, -2 if fails to connect. Definition at line 244 of file server-client.c.

int close_socket (  int  sd  )

Close socket. Parameters: sd  [in] socket descriptor to close Returns: 0 on success, -1 on failure. Definition at line 277 of file server-client.c. Referenced by adin_tcpip_end(), and main_module_loop().

void cleanup_socket (   )

Clean up socket data at program exit. Definition at line 293 of file server-client.c. Referenced by j_error(), and j_exit().
