NAME gnutls_record_recv - API function
SYNOPSIS #include <gnutls/gnutls.h>
ssize_t gnutls_record_recv(gnutls_session_t session, void * data, size_t sizeofdata);
ARGUMENTS gnutls_session_t session is a gnutls_session_t structure.
void * data the buffer that the data will be read into
size_t sizeofdata the number of requested bytes
DESCRIPTION This function has the similar semantics with recv(). The only differ- ence is that it 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 GNUTLS_A_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 recv()) then GNUTLS_E_INTERRUPTED will be returned. If GNUTLS_E_INTER- RUPTED or GNUTLS_E_AGAIN is returned, you must call this function again to get the data. See also gnutls_record_get_direction().
A server may also receive GNUTLS_E_REHANDSHAKE when a client has initi- ated 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 sizeofdata.
