gnutls_x509_crq_get_extension_data(3)                                   gnutls

NAME
       gnutls_x509_crq_get_extension_data - API function

SYNOPSIS
       #include <gnutls/x509.h>

       int gnutls_x509_crq_get_extension_data(gnutls_x509_crq_t crq, unsigned
       indx, void * data, size_t * sizeof_data);

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 * data a pointer to a structure to hold the data (may be null)

       size_t * sizeof_data
                   initially holds the size of  oid

DESCRIPTION
       This function will return the requested extension data in the
       certificate.  The extension data will be stored as a string in the
       provided buffer.

       Use gnutls_x509_crq_get_extension_info() to extract the OID and
       critical flag.  Use gnutls_x509_crq_get_extension_by_oid() instead, if
       you want to get data indexed by the extension OID rather than sequence.

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
