SYNOPSIS        top

#include <gnutls/gnutls.h>int gnutls_dh_params_export_pkcs3(gnutls_dh_params_tparams,gnutls_x509_crt_fmt_tformat, unsigned char *params_data, size_t*params_data_size);

ARGUMENTS        top

       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)

       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".
