NAME
       gnutls_x509_crq_get_extension_info - API function


SYNOPSIS
       #include <gnutls/x509.h>

       int  gnutls_x509_crq_get_extension_info(gnutls_x509_crq_t  crq,  unsigned  indx,  void  *  oid,  size_t *
       sizeof_oid, unsigned int * critical);


ARGUMENTS
       gnutls_x509_crq_t crq
                   should contain a gnutls_x509_crq_t type

       unsigned indx
                   Specifies which extension number to get. Use (0) to get the first one.

       void * oid  a pointer to store the OID

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

       unsigned 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_crq_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  (0) is returned, otherwise a negative error code in case of an error.  If
       your have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.


SINCE
       2.8.0
