NAME

       gnutls_x509_crt_get_extension_info - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int  gnutls_x509_crt_get_extension_info(gnutls_x509_crt_t  cert,  int  indx,  void  * oid,
       size_t * sizeof_oid, int * critical);

ARGUMENTS

       gnutls_x509_crt_t cert
                   should contain a gnutls_x509_crt_t structure

       int indx    Specifies which extension OID to send. Use zero to get the first one.

       void * oid  a pointer to a structure to hold the OID

       size_t * sizeof_oid
                   initially holds the maximum size of oid, on return holds actual size of oid.

       int * critical
                   output variable with critical flag, may be NULL.

DESCRIPTION

       This function will return the requested extension OID in the certificate, and the critical
       flag  for  it.   The extension OID will be stored as a string in the provided buffer.  Use
       gnutls_x509_crt_get_extension_data() to extract the data.

       If the buffer provided is not long enough to hold the output, then *sizeof_oid is  updated
       and GNUTLS_E_SHORT_MEMORY_BUFFER will be returned.

RETURNS

       On  success, GNUTLS_E_SUCCESS (zero) is returned, otherwise an error code is returned.  If
       you have reached the last extension available  GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE  will
       be returned.
