Constant and global variable mappings

These generic-text constant, global variable, and standard-type mappings are defined in TCHAR.H and depend on whether the constant _UNICODE or _MBCS has been defined in your program.

Generic-text constant and global variable mappings

Generic-text - object name	SBCS (_UNICODE, _MBCS not defined)	_MBCS defined	_UNICODE defined
_TEOF	EOF	EOF	WEOF
_tenviron	_environ	_environ	_wenviron
_tpgmptr	_pgmptr	_pgmptr	_wpgmptr
