    dhminlen: usize,
) -> c_int

\brief This function parses DHM parameters in PEM or DER format.

\param dhm The DHM context to import the DHM parameters into. This must be initialized. \param dhmin The input buffer. This must be a readable buffer of length \p dhminlen Bytes. \param dhminlen The size of the input buffer \p dhmin, including the terminating \c NULL Byte for PEM data.
