Api function
Usage
#include <gnutls/x509.h>
int gnutls_x509_crq_get_key_purpose_oid(gnutls_x509_crq_t crq, unsigned indx, void * oid, size_t * sizeof_oid, unsigned int * critical);
Arguments
gnutls_x509_crq_t crq
|
should contain a |
|---|---|
unsigned indx
|
This specifies which OID to return, use (0) to get the first one |
void * oid
|
a pointer to store 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. |
