NAME

6       gnutls_record_send - sends to the peer the specified data
7

SYNOPSIS

9       #include <gnutls/gnutls.h>
10
11       ssize_t gnutls_record_send(gnutls_session_t session, const void * data,
12       size_t sizeofdata);
13

ARGUMENTS

15       gnutls_session_t session
16                   is a gnutls_session_t structure.
17
18       const void * data
19                   contains the data to send
20
21       size_t sizeofdata
22                   is the length of the data
23

DESCRIPTION

25       This function has the similar semantics with send().  The only  differ‐
26       ence  is  that  it  accepts  a GnuTLS session, and uses different error
27       codes.
28
29       Note that if the send buffer is full, send() will block this  function.
30       See the send() documentation for full information.  You can replace the
31       default push function by using gnutls_transport_set_ptr2() with a  call
32       to send() with a MSG_DONTWAIT flag if blocking is a problem.
33
34       If  the EINTR is returned by the internal push function (the default is
35       send()} then GNUTLS_E_INTERRUPTED will be returned. If  GNUTLS_E_INTER‐
36       RUPTED  or  GNUTLS_E_AGAIN  is  returned,  you  must call this function
37       again, with the same parameters; alternatively you could provide a NULL
38       pointer for data, and 0 for size. cf. gnutls_record_get_direction().
39

RETURNS

41       the  number  of  bytes  sent,  or a negative error code.  The number of
42       bytes sent might be less than sizeofdata.  The maximum number of  bytes
43       this function can send in a single call depends on the negotiated maxi‐
44       mum record size.
