hal_param_alias(3hal)

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.
