gnutls_record_send — sends to the peer the specified data

gnutls_session_t | session, |
| const void * | data, | |
| size_t | sizeofdata); |
is a gnutls_session_t structure.
contains the data to send
is the length of the data
This function has the similar semantics with send(). The only difference is that is
accepts a GNUTLS session, and uses different error codes.
Note that if the send buffer is full, send() will block this function. See the
send() documentation for full
information. You can replace the default push function by
using gnutls_transport_set_ptr2() with a call to
send() with a MSG_DONTWAIT flag
if blocking is a problem.
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. cf. gnutls_record_get_direction().
the number of bytes sent, or a negative error code. The
number of bytes sent might be less than sizeofdata. The maximum number
of bytes this function can send in a single call depends on
the negotiated maximum record size.
The full documentation for gnutls is maintained as a Texinfo manual. If the info and gnutls programs are properly installed at your site, the command
info gnutls
should give you access to the complete manual.
