Locale-Sensitive C/C++ String Operation Function
char *getenv(const char* varname);
wchar_t *_wgetenv(const wchar_t* varname);
TCHAR *_tgetenv(const TCHAR* varname);
Internationalization (I18n) Function Overview
The getenv function returns a pointer to the environment table entry containing varname , or NULL if varname is not found. On Windows, the match is case-insensitive, treating lowercase characters as if they were uppercase.
Only Windows platforms supply a wide-character version of this call - _wgetenv . The argument and return value are both wide-character strings.
_tgetenv is the Windows-only Generic version of the function; with the _MBCS or _UNICODE compiler flags determining its mapping to either getenv or _wgetenv .
I18n Issues
Use the appropriate version of the function as required for internationalization support, noting the following:
On ANSI platforms, there is no corresponding wide function call. Instead, use string conversion routines and call getenv .
For Windows MBCS support, ensure that the multibyte code page is set properly, as getenv depends on it. By default, the multibyte code page is set to the system-default ANSI code page obtained from the operating system at program startup. Use _getmbcp and _setmbcp to query or change the current multibyte code page, respectively.
