pub unsafe extern "C" fn mbedtls_md_free(
    ctx: *mut mbedtls_md_context_t
)
Expand description

\brief This function clears the internal structure of \p ctx and frees any embedded internal structure, but does not free \p ctx itself.

             If you have called mbedtls_md_setup() on \p ctx, you must
             call mbedtls_md_free() when you are no longer using the
             context.
             Calling this function if you have previously
             called mbedtls_md_init() and nothing else is optional.
             You must not call this function if you have not called
             mbedtls_md_init().
