NAME

gnutls_x509_crq_get_key_purpose_oid - API function

#include <gnutls/x509.h>

int gnutls_x509_crq_get_key_purpose_oid(gnutls_x509_crq_t crq, int indx, void * oid, size_t * sizeof_oid, unsigned int * critical);

ARGUMENTS

gnutls_x509_crq_t crq

should contain a gnutls_x509_crq_t structure

int indx

This specifies which OID to return, use (0) to get the first one

void * oid

a pointer to a buffer to hold the OID (may be NULL)

size_t * sizeof_oid

initially holds the size of oid

unsigned int * critical

output variable with critical flag, may be NULL.
