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 structure.
- 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 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_INTERRUPTED
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 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 (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 .
