Query number of bytes in TLS buffers.

fb_gnutls_cleanup()

void fb_gnutls_cleanup

(

)

fb_gnutls_configure()

bool fb_gnutls_configure

(

const FB_TLS_CONFIG_FILENAMES *

paths

)

Initialize state, load certificates and keys.

fb_gnutls_done()

fb_gnutls_read()

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

Read data from a TLS connection using GNU TLS.

fb_gnutls_write()

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

Write data to a TLS connection using GNU TLS.
