NAME
gnutls_x509_crt_get_key_purpose_oid - This function returns the Certificate's key purpose OIDs
SYNOPSIS
#include <gnutls/x509.h>
I int gnutls_x509_crt_get_key_purpose_oid(gnutls_x509_crt_t cert , int indx , void * oid , size_t * sizeof_oid , unsigned int * critical );
ARGUMENTS
"gnutls_x509_crt_t
should contain a gnutls_x509_crt_t structure
"int
This specifies which OID to return. Use zero to get the first one.
"void
a pointer to a buffer to hold the OID (may be null)
"size_t
initially holds the size of oid
"unsigned
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.
Returns GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not
long enough, and in that case the *sizeof_oid will be updated with
the required size. On success 0 is returned.
