NAME
bio - Basic I/O abstraction

SYNOPSIS
#include <openssl/bio.h>

DESCRIPTION
A BIO is an I/O abstraction, it hides many of the underlying I/O details
from an application. If an application uses a BIO for its I/O it can
transparently handle SSL connections, unencrypted network connections
and file I/O.

There are two type of BIO, a source/sink BIO and a filter BIO.

As its name implies a source/sink BIO is a source and/or sink of data,
examples include a socket BIO and a file BIO.

EXAMPLES
Create a memory BIO:

BIO *mem = BIO_new(BIO_s_mem());
