gnutls_x509_crq_get_extension_by_oid — get the specified extension
#include <gnutls/x509.h>
int gnutls_x509_crq_get_extension_by_oid( |
gnutls_x509_crq_t crq, |
| const char * oid, | |
| int indx, | |
| void * buf, | |
| size_t * sizeof_buf, | |
unsigned int * critical); |
should contain a gnutls_x509_crq_t structure
holds an Object Identified in null terminated string
In case multiple same OIDs exist in the extensions, this specifies which to send. Use zero to get the first one.
a pointer to a structure to hold the name (may be null)
initially holds the size of buf
will be non zero if the extension is marked as critical
This function will return the extension specified by the OID in the certificate. The extensions will be returned as binary data DER encoded, in the provided buffer.
On success, GNUTLS_E_SUCCESS is returned, otherwise a negative value in case of an error. If the certificate does not contain the specified extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
