gnutls_ia_recv(3)		    gnutls		     gnutls_ia_recv(3)

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 it 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 applica‐
       tion phase finished message has been sent by the server.
