gnutls_record_recv(3) gnutls gnutls_record_recv(3) NAME gnutls_record_recv - API function SYNOPSIS #include <gnutls/gnutls.h> ssize_t gnutls_record_recv(gnutls_session_t session, void * data, size_t data_size); ARGUMENTS gnutls_session_t session is a gnutls_session_t type. void * data the buffer that the data will be read into size_t data_size the number of requested bytes DESCRIPTION This function has the similar semantics with recv(). 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 of GNUTLS_E_REHANDSHAKE. In case of a client, this message may be simply ignored, replied with an alert GNUTLS_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. If EINTR is returned by the internal pull function (the default is 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 gnutls_record_get_direction(). RETURNS 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 requested data_size . REPORTING BUGS Report bugs to <bugs@gnutls.org>.
