NAME
gnutls_ia_send - API function
SYNOPSIS
#include <gnutls/extra.h>
ssize_t gnutls_ia_send(gnutls_session_t session, const char * data, size_t sizeofdata);
ARGUMENTS
| gnutls_session_t session | is a gnutls_session_t structure. |
| const char * data | contains the data to send |
| size_t sizeofdata | is the length of the data |
DESCRIPTION
Send TLS/IA application payload data. This function has the similar semantics with send(). The only difference is that is accepts a GNUTLS session, and uses different error codes.
The TLS/IA protocol is synchronous, so you cannot send more than one packet at a time. The client always send the first packet.
To finish an application phase in the server, use gnutls_ia_endphase_send(). The client cannot end an application phase unilaterally; rather, a client is required to respond with an endphase of its own if gnutls_ia_recv indicates that the server has sent one.
If the EINTR is returned by the internal push function (the default is send()} 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 sent, or a negative error code.
