NAME

       hal_param_alias - create an alternate name for a param

SYNTAX

       int hal_param_alias(const char *original_name, const char *alias);

ARGUMENTS

       original_name
              The original name of the param

       alias  The  alternate  name  that may be used to refer to the param, or NULL to remove any
              alternate name.

DESCRIPTION

       A param may have two names: the original name (the one that was passed to a  hal_param_new
       function) and an alias.

       Usually,  aliases are for the convenience of users and should be created and destroyed via
       halcmd.  However, in some cases it is sensible to create aliases directly in a  component.
       These  cases include the case where a param is renamed, to preserve compatibility with old
       versions.

RETURN VALUE

       Returns a HAL status code.
