NAME         top

       gnutls_x509_crq_get_extension_info - API function

SYNOPSIS         top

       #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         top

       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         top

       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         top

       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.
