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_verify_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
       provide 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.

NAME

       gnutls_record_recv_seq - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       ssize_t gnutls_record_recv_seq(gnutls_session_t session, void * data, size_t data_size, unsigned char * seq);

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

       unsigned char * seq
		   is the packet's 64-bit sequence number. Should have space for 8 bytes.

DESCRIPTION

       This  function  is  the same as gnutls_record_recv(), except that it returns in addition to data, the sequence number of the data.  This is
       useful in DTLS where record packets might be received out-of-order. The returned 8-byte sequence number is an integer in big-endian  format
       and should be treated as a unique message identification.

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  data_size .

SINCE

       3.0
