NAME
  BIO_ctrl_get_read_request - Find out how many bytes were requested from the
  BIO

SYNOPSIS
  #include <openssl/bio.h>

  size_t BIO_ctrl_get_read_request(
	  BIO *bio );

DESCRIPTION
  The BIO_ctrl_get_read_request() function returns the number of bytes that
  were last requested from bio by a BIO_read() operation. This is useful for
  BIO pairs, for example, so that the application knows how many bytes to
  supply to bio.

NOTES
  When bio is NULL, the OpenSSL library calls assert().

RETURN VALUES
  The following return values can occur:

  >=0	  The number of bytes requested.
