NAME

6       gnutls_ext_raw_parse - API function
7

SYNOPSIS

9       #include <gnutls/gnutls.h>
10
11       int  gnutls_ext_raw_parse(void  *  ctx, gnutls_ext_raw_process_func cb,
12       const gnutls_datum_t * data, unsigned int flags);
13

ARGUMENTS

15       void * ctx  a pointer to pass to callback function
16
17       gnutls_ext_raw_process_func cb
18                   callback function to process each extension found
19
20       const gnutls_datum_t * data
21                   TLS extension data
22
23       unsigned int flags
24                   should be zero or  GNUTLS_EXT_RAW_FLAG_TLS_CLIENT_HELLO  or
25                   GNUTLS_EXT_RAW_FLAG_DTLS_CLIENT_HELLO
26

DESCRIPTION

28       This function iterates through the TLS extensions as passed in
29        data , passing the individual extension data to callback. The
30        data must conform to Extension extensions<0..2^16-1> format.
31
32       If  flags  is  GNUTLS_EXT_RAW_TLS_FLAG_CLIENT_HELLO  then this function
33       will parse the extension data from the position, as if the packet in
34        data is a client hello (without record or handshake headers) - as pro‐
35       vided by gnutls_handshake_set_hook_function().
36
37       The return value of the callback will be propagated.
38

RETURNS

40       GNUTLS_E_SUCCESS  on  success,  or  an  error code. On unknown flags it
41       returns GNUTLS_E_INVALID_REQUEST.
