.SH NAME
gnutls_ext_raw_parse \- API function
.SH SYNOPSIS
.B #include <gnutls/gnutls.h>
.sp
.BI "int gnutls_ext_raw_parse(void * " ctx ", gnutls_ext_raw_process_func " cb ", const gnutls_datum_t * " data ", unsigned int " flags ");"
.SH ARGUMENTS
.IP "void * ctx" 12
a pointer to pass to callback function
.IP "gnutls_ext_raw_process_func cb" 12
callback function to process each extension found
.IP "const gnutls_datum_t * data" 12
TLS extension data
.IP "unsigned int flags" 12
should be zero or \fBGNUTLS_EXT_RAW_FLAG_TLS_CLIENT_HELLO\fP or \fBGNUTLS_EXT_RAW_FLAG_DTLS_CLIENT_HELLO\fP
.SH "DESCRIPTION"
This function iterates through the TLS extensions as passed in
 \fIdata\fP , passing the individual extension data to callback. The
 \fIdata\fP must conform to Extension extensions<0..2^16\-1> format.

If flags is \fBGNUTLS_EXT_RAW_TLS_FLAG_CLIENT_HELLO\fP then this function
will parse the extension data from the position, as if the packet in
 \fIdata\fP is a client hello (without record or handshake headers) \-
as provided by \fBgnutls_handshake_set_hook_function()\fP.

The return value of the callback will be propagated.
.SH "RETURNS"
\fBGNUTLS_E_SUCCESS\fP on success, or an error code. On unknown
flags it returns \fBGNUTLS_E_INVALID_REQUEST\fP.
.SH "SINCE"
