Function Documentation

fb_cleanup_tls_support()

void fb_cleanup_tls_support

(

void

)

Here is the caller graph for this function:

fb_file_done()

void fb_file_done

(

FB_CONNECTION *

connection

)

Wrap up reading from a file.

fb_file_init()

bool fb_file_init

(

struct fb_connection_t *

connection

)

Prepare to read from a file in the guise of a connection.

fb_file_read()

ssize_t fb_file_read	(	struct fb_connection_t *	connection,
		char *	data,
		ssize_t	byte_count
	)

Read data from an unencrypted BSD Sockets connection.

fb_file_write()

ssize_t fb_file_write	(	struct fb_connection_t *	connection,
		const char *	data,
		ssize_t	byte_count
	)

Send writes to the logfile when reading from a file.

fb_init_tls_support()

bool fb_init_tls_support

(

const char *

path

)

Here is the caller graph for this function:

fb_unencrypted_buffering()

ssize_t fb_unencrypted_buffering

(

struct fb_connection_t *

connection

)

Query number of bytes in TLS buffers.

fb_unencrypted_done()

Close an unencrypted BSD Sockets connection.

fb_unencrypted_handshake()

ssize_t fb_unencrypted_handshake

(

struct fb_connection_t *

connection

)

Perform TLS handshaking on a new connection. Return incomplete, failure, or 0.

fb_unencrypted_init()

bool fb_unencrypted_init

(

struct fb_connection_t *

connection

)

Initialize an unencrypted BSD sockets connection.

fb_unencrypted_read()

ssize_t fb_unencrypted_read	(	struct fb_connection_t *	connection,

Write data to an unencrytped BSD Sockets connection.

Variable Documentation

FB_TRANSPORT_CLOSED

const ssize_t FB_TRANSPORT_CLOSED = 0

Connection closed normally. Returned by read transport function only.

FB_TRANSPORT_FAILURE

const ssize_t FB_TRANSPORT_FAILURE = -2

An action failed permanently; the connection has failed and should be closed.

FB_TRANSPORT_INCOMPLETE

const ssize_t FB_TRANSPORT_INCOMPLETE = -1

An action was incomplete, but can be retried in the future.

    .read = fb_file_read,
    .write = fb_file_write,
    .done = fb_file_done
}

Transport virtual method table for reading from files.

fb_transport_unencrypted

Initial value:

= {
    .init = fb_unencrypted_init,
    .handshake = fb_unencrypted_handshake,
    .buffering = fb_unencrypted_buffering,
    .read = fb_unencrypted_read,
    .write = fb_unencrypted_write,
