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_WARNING_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.
