NAME
gnutls_record_recv - reads data from the TLS record protocol
SYNOPSIS
#include <gnutls/gnutls.h>
I ssize_t gnutls_record_recv(gnutls_session_t session , void * data , size_t sizeofdata );
ARGUMENTS
"gnutls_session_t
is a gnutls_session_t structure.
"void
the buffer that the data will be read into
"size_t
the number of requested bytes
DESCRIPTION
This function has the similar semantics with recv(). The only
difference is that is accepts a GNUTLS session, and uses different
error codes.
In the special case that a server requests a renegotiation, the
client may receive an error code of GNUTLS_E_REHANDSHAKE. This
message may be simply ignored, replied with an alert containing
NO_RENEGOTIATION, or replied with a new handshake, depending on
the client's will.
If EINTR is returned by the internal push function (the default is
code{recv()}) then GNUTLS_E_INTERRUPTED will be returned. If
GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN is returned, you must
call this function again to get the data. See also
code{gnutls_record_get_direction()}.
A server may also receive GNUTLS_E_REHANDSHAKE when a client has
initiated a handshake. In that case the server can only initiate a
handshake or terminate the connection.
Returns the number of bytes received and zero on EOF. A negative
error code is returned in case of an error. The number of bytes
received might be less than code{count}.
