NAME        top

       gnutls_record_recv - API function

SYNOPSIS        top

#include <gnutls/gnutls.h>ssize_t gnutls_record_recv(gnutls_session_tsession, void *data,size_tdata_size);

ARGUMENTS        top

       gnutls_session_t session                   is agnutls_session_ttype.       void * data the buffer that the data will be read into       size_t data_size                   the number of requested bytes

DESCRIPTION        top

       This function has the similar semantics withrecv().  The only       difference is that it accepts a GnuTLS session, and uses different       error codes.  In the special case that the peer requests a       renegotiation, the caller will receive an error code ofGNUTLS_E_REHANDSHAKE.  In case of a client, this message may be       simply ignored, replied with an alertGNUTLS_A_NO_RENEGOTIATION,       or replied with a new handshake, depending on the client's will. A       server receiving this error code can only initiate a new handshake       or terminate the session.       IfEINTRis returned by the internal pull function (the default isrecv()) thenGNUTLS_E_INTERRUPTEDwill be returned.  IfGNUTLS_E_INTERRUPTEDorGNUTLS_E_AGAINis returned, you must call       this function again to get the data.  See alsognutls_record_get_direction().

RETURNS        top

       The number of bytes received and zero on EOF (for stream       connections).  A negative error code is returned in case of an       error.  The number of bytes received might be less than the       requesteddata_size .
