-=head1 NAME
-
-SSL_read - write bytes to a TLS/SSL connection.
-
-=head1 SYNOPSIS
-
- #include <openssl/ssl.h>
-
- int SSL_write(SSL *ssl, char *buf, int num);
-
-=head1 DESCRIPTION
-
-SSL_write() writes B<num> bytes from the buffer B<buf> into the specified
-B<ssl> connection.
-
-=head1 NOTES
-
-If necessary, SSL_write() will negotiate a TLS/SSL session, if
-not already explicitly performed by SSL_connect() or SSL_accept(). If the
-peer requests a re-negotiation, it will be performed transparently during
-the SSL_write() operation. The behaviour of SSL_write() depends on the
-underlying BIO.
-
-If the underlying BIO is B<blocking>, SSL_write() will only return, once the
-write operation has been finished or an error occurred.
-
-If the underlying BIO is B<non-blocking>, SSL_write() will also return,
-when the underlying BIO could not satisfy the needs of SSL_write()
-to continue the operation. In this case a call to SSL_get_error() with the
-return value of SSL_write() will yield B<SSL_ERROR_WANT_READ> or
-B<SSL_ERROR_WANT_WRITE>. As at any time a re-negotiation is possible, a
-call to SSL_write() can also cause write operations! The calling process
-then must repeat the call after taking appropriate action to satisfy the
-needs of SSL_write(). The action depends on the underlying BIO. When using a
-non-blocking socket, nothing is to be done, but select() can be used to check
-for the required condition. When using a buffering BIO, like a BIO pair, data
-must be written into or retrieved out of the BIO before being able to continue.
-
-=head1 WARNING
-
-When an SSL_write() operation has to be repeated because of
-B<SSL_ERROR_WANT_READ> or B<SSL_ERROR_WANT_WRITE>, it must be repeated
-with the same arguments.
-
-=head1 RETURN VALUES
-
-The following return values can occur:
-
-=over 4
-
-=item E<gt>0
-
-The write operation was successful, the return value is the number of
-bytes actually written to the TLS/SSL connection.
-
-=item 0
-
-The write operation was not successful. Call SSL_get_error() with the return
-value B<ret> to find out, whether an error occurred.
-
-=item -1
-
-The read operation was not successful, because either an error occurred
-or action must be taken by the calling process. Call SSL_get_error() with the
-return value B<ret> to find out the reason.
