gnutls_ia_recv - read data from the TLS/IA protocol

#include <gnutls/extra.h> I ssize_t gnutls_ia_recv(gnutls_session_t session , char * data , size_t sizeofdata );

"gnutls_session_t is a gnutls_session_t structure.

"char the buffer that the data will be read into, must hold >= 12 bytes.

"size_t the number of requested bytes, must be >= 12.

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_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.
