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.
