int gnutls_dh_params_export_pkcs3(gnutls_dh_params_t params, gnutls_x509_crt_fmt_t format, unsigned char * params_data, size_t * params_data_size);
ARGUMENTS
gnutls_dh_params_t params
Holds the DH parameters
gnutls_x509_crt_fmt_t format
the format of output params. One of PEM or DER.
unsigned char * params_data
will contain a PKCS3 DHParams structure PEM or DER encoded
size_t * params_data_size
holds the size of params_data (and will be replaced by the actual size of parameters)
DESCRIPTION
This function will export the given dh parameters to a PKCS3
DHParams structure. This is the format generated by "openssl dhparam" tool.
If the buffer provided is not long enough to hold the output, then
GNUTLS_E_SHORT_MEMORY_BUFFER will be returned.
If the structure is PEM encoded, it will have a header
of "BEGIN DH PARAMETERS".
RETURNS
On success, GNUTLS_E_SUCCESS (zero) is returned,
otherwise an error code is returned.
