NAME
       gnutls_x509_crq_get_extension_by_oid - API function

SYNOPSIS
       #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 * buf_size, unsigned int *
       critical);

ARGUMENTS
       gnutls_x509_crq_t crq
                   should contain a gnutls_x509_crq_t type

       const char * oid
                   holds an Object Identifier in a null terminated string

       int indx    In case multiple same OIDs exist in the extensions, this
                   specifies which to get. Use (0) to get the first one.

       void * buf  a pointer to a structure to hold the name (may be null)

       size_t * buf_size
                   initially holds the size of  buf

       unsigned int * critical
                   will be non-zero if the extension is marked as critical

DESCRIPTION
       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.

RETURNS
       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error
       code in case of an error.  If the certificate does not contain the
       specified extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be
       returned.

SINCE
       2.8.0
