       gnutls_x509_crt_export - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int  gnutls_x509_crt_export(gnutls_x509_crt_t  cert,  gnutls_x509_crt_fmt_t format, void *
       output_data, size_t * output_data_size);

ARGUMENTS

       gnutls_x509_crt_t cert
                   Holds the certificate

       gnutls_x509_crt_fmt_t format
                   the format of output params. One of PEM or DER.

       void * output_data
                   will contain a certificate PEM or DER encoded

       size_t * output_data_size
                   holds the size of output_data (and will be replaced  by  the  actual  size  of
                   parameters)

DESCRIPTION

       This function will export the certificate to DER or PEM format.

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

       If the structure is PEM encoded, it will have a header of "BEGIN CERTIFICATE".

RETURNS

       In case of failure a negative error code will be returned, and 0 on success.
