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

SYNOPSIS    [Toc]    [Back]

       size_t BIO_ctrl_get_read_request(
               BIO *bio );

DESCRIPTION    [Toc]    [Back]

       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    [Toc]    [Back]

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

       requested.
