Description

The function read-dhparams reads or uses cached DH parameters.

filename specifies the file to check.

Unless force is true, read-dhparams checks whether the file filename has already been loaded, and if it has been loaded, uses the cached value.

If force is true, or if there is no cached value for filename, read-dhparams loads the file by calling pem-read with thing-to-read argument "DHparams", pass-phrase, callback and errorp. read-dhparams caches and returns a foreign pointer to the resulting DH structure (that is, a pointer corresponding to the C type DH*).

If read-dhparams fails to load the file filename, if errorp is true it signals an error, otherwise it returns nil. The default value of errorp is t.
