SYNOPSIS
#include <gnutls/x509.h>
int gnutls_x509_crt_get_extension_oid(gnutls_x509_crt_t cert, unsigned indx, void * oid, size_t * oid_size);
ARGUMENTS
- gnutls_x509_crt_t cert
- should contain a gnutls_x509_crt_t type
- unsigned indx
- Specifies which extension OID to send. Use (0) to get the first one.
- void * oid
- a pointer to a structure to hold the OID (may be null)
- size_t * oid_size
- initially holds the size of oid
DESCRIPTION
This function will return the requested extension OID in the certificate. The extension OID will be stored as a string in the provided buffer.
The oid returned will be null terminated, although oid_size will not account for the trailing null.
