NAME

gnutls_x509_crt_get_extension_data - Get the specified extension data  

SYNOPSIS

#include <gnutls/x509.h>

int gnutls_x509_crt_get_extension_data(gnutls_x509_crt_t cert, int indx, void * data, size_t * sizeof_data);  

ARGUMENTS

gnutls_x509_crt_t cert
should contain a gnutls_x509_crt_t structure
int indx
Specifies which extension OID to send. Use zero to get the first one.
void * data
a pointer to a structure to hold the data (may be null)
size_t * sizeof_data
initially holds the size of oid
 

DESCRIPTION

This function will return the requested extension data in the certificate. The extension data will be stored as a string in the provided buffer.

Use gnutls_x509_crt_get_extension_info() to extract the OID and critical flag. Use gnutls_x509_crt_get_extension_by_oid() instead, if you want to get data indexed by the extension OID rather than sequence.  

RETURNS

On success, GNUTLS_E_SUCCESS (zero) is returned, otherwise an error code is returned. If you have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
