NAME
gnutls_x509_crt_get_key_purpose_oid - API function
SYNOPSIS
#include <gnutls/x509.h>
gnutls_x509_crt_get_key_purpose_oid(3) cert,
unsigned indx, void * oid, size_t * oid_size, unsigned int * critical);
ARGUMENTS
gnutls_x509_crt_t cert
should contain a gnutls_x509_crt_t type
unsigned 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 * oid_size
initially holds the size of oid
unsigned int * critical
output flag to indicate criticality of extension
DESCRIPTION
This function will extract the key purpose OIDs of the Certificate
specified by the given index. These are stored in the Extended Key
Usage extension (2.5.29.37) See the GNUTLS_KP_* definitions for human
readable names.
If oid is null then only the size will be filled. The oid returned
will be null terminated, although oid_size will not account for the
trailing null.
RETURNS
GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long enough,
and in that case the *oid_size will be updated with the required size.
On success 0 is returned.
