SYNOPSIS

#include <gnutls/x509.h>

int gnutls_x509_crq_get_extension_data(gnutls_x509_crq_t crq, unsigned indx, void * data, size_t * sizeof_data);

gnutls_x509_crq_t crq

unsigned indx

Specifies which extension number to get. Use (0) 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_crq_get_extension_info() to extract the OID and critical flag. Use gnutls_x509_crq_get_extension_by_oid() instead, if you want to get data indexed by the extension OID rather than sequence.
