Function Documentation

int SPDYF_raw_after_write ( struct SPDY_Session session,
int  was_written 
)

Unsets TCP_CORK.

Parameters:
session 
was_written has the same value as the write function for the session will return
Returns:
returned value will be used by the write function to return

Parameters:
session 
Returns:
SPDY_NO if writing must not happen in the call; SPDY_YES otherwise

void SPDYF_raw_close_session ( struct SPDY_Session session  ) 

Should be called closing session's socket.

Parameters:
session SPDY_Session whose socket is used

void SPDYF_raw_deinit ( struct SPDY_Daemon daemon  ) 

Should be called when the deamon is stopped.

Parameters:
daemon SPDY_Daemon which is being stopped

Here is the caller graph for this function:

int SPDYF_raw_init ( struct SPDY_Daemon daemon  ) 

Must be called when the daemon starts.

Parameters:
daemon SPDY_Daemon
Returns:
SPDY_YES on success or SPDY_NO on error

Here is the caller graph for this function:

int SPDYF_raw_is_pending ( struct SPDY_Session session  ) 

Checks if there is data staying in the buffers of the underlying system that waits to be read. Always returns SPDY_NO, as we do not use a subsystem here.

Parameters:
session which is checked
Returns:
SPDY_YES if data is pending or SPDY_NO otherwise

Definition at line 151 of file io_raw.c.

References SPDY_NO.

Here is the caller graph for this function:

int SPDYF_raw_new_session ( struct SPDY_Session session  ) 

Must be called after the connection has been accepted.

Parameters:
session SPDY_Session whose socket will be used
Returns:
SPDY_NO if some funcs fail. SPDY_YES otherwise

Here is the caller graph for this function:

int SPDYF_raw_recv ( struct SPDY_Session session,
void *  buffer,
size_t  size 
)

Reading from socket. Reads available data and put it to the buffer.

Parameters:
session for which data is received
buffer where data from the socket will be written to
size of the buffer
Returns:
number of bytes (at most size) read from the connection 0 if the other party has closed the connection SPDY_IO_ERROR code on error

Here is the caller graph for this function:

int SPDYF_raw_send ( struct SPDY_Session session,
const void *  buffer,
size_t  size 
)

Writing to socket. Writes the data given into the buffer to the socket.

Parameters:
session whose context is used
buffer from where data will be written to the socket
size number of bytes to be taken from the buffer
Returns:
number of bytes (at most size) from the buffer that has been written to the connection 0 if the other party has closed the connection SPDY_IO_ERROR code on error
