NAME
gnutls_ia_recv - read data from the TLS/IA protocol
SYNOPSIS
#include <gnutls/extra.h>
ssize_t gnutls_ia_recv(gnutls_session_t session, char * data, size_t
sizeofdata);
ARGUMENTS
gnutls_session_t session
is a gnutls_session_t structure.
char * data the buffer that the data will be read into, must hold >= 12
bytes.
size_t sizeofdata
the number of requested bytes, must be >= 12.
DESCRIPTION
Receive TLS/IA data. This function has the similar semantics with
recv(). The only difference is that is accepts a GNUTLS session, and
uses different error codes.
If the server attempt to finish an application phase, this function
will return GNUTLS_E_WARNING_IA_IPHF_RECEIVED or GNUTLS_E_WARN‐
ING_IA_FPHF_RECEIVED. The caller should then invoke gnutls_ia_ver‐
ify_endphase(), and if it runs the client side, also send an endphase
message of its own using gnutls_ia_endphase_send.
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, with the same parameters; alternatively you could pro‐
vide a NULL pointer for data, and 0 for size.
Returns the number of bytes received. A negative error code is
returned in case of an error. The GNUTLS_E_WARNING_IA_IPHF_RECEIVED
and GNUTLS_E_WARNING_IA_FPHF_RECEIVED errors are returned when an
application phase finished message has been sent by the server.
