/* _defs.h
Common definitions for pointer size and calling conventions.
Calling conventions:
_RTLENTRY Specifies the calling convention used by the RTL
_USERENTRY Specifies the calling convention the RTL expects user
compiled functions to use (for callbacks)
Export (and size for DOS) information:
_EXPCLASS Exports class if building DLL version of library
For DOS16 also provides size information
_EXPDATA Exports data if building DLL version of library
_EXPFUNC Exports function if building DLL version of library
For DOS16 also provides size information
_FAR Promotes data pointers to far in DLLs (DOS16 only)
Obsolete versions:
_Cdecl Use _RTLENTRY
_CLASSTYPE Use _EXPCLASS
_FARFUNC Use _EXPFUNC
_FARCALL Use _EXPFUNC and declare function explicity __far
