SYNOPSIS

Provides a uniform way to declare ALIASs or SYNONYMS for global symbols. The implementation is platform dependant, however the macros are universal.

USAGE

Suppose one has a facility ORG_ containing the routines ORG_get, ORG_set. Aliases ALIAS_get and ALIAS_set can be created using the following prescription.

   ALIAS_BEG(ORG_)
   ALIAS_FNC(int, ORG_get, ALIAS_get)
   ALIAS_FNC(int, ORG_set, ALIAS_set)
   ALIAS_END(ORG_)

TARGET PLATFORMS

All FSW supported platforms.

LIMITATIONS

Some platforms demand that the symbol being aliased be defined in the same file where the aliasing is occurring. This is an unfortunate limitation. One cannot, for example, alias a symbol to a system routine.
