NAME

       hal_pin_alias - create an alternate name for a pin

SYNTAX

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

ARGUMENTS

       original_name
              The original name of the pin

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

DESCRIPTION

       A pin may have two names: the original name (the one that  was  passed  to  a  hal_pin_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 pin is renamed, to preserve compatibility with old
       versions.

RETURN VALUE

       Returns a HAL status code.
