#include <gnutls/x509.h>
int gnutls_x509_crq_get_extension_info(gnutls_x509_crq_t crq, unsigned
indx, void * oid, size_t * sizeof_oid, unsigned int * critical);
ARGUMENTS

unsigned indx
Specifies which extension number to get. Use (0) to get the

size_t * sizeof_oid
initially holds the maximum size of oid , on return holds
actual size of oid .
unsigned int * critical
