Locale-Sensitive C/C++ String Operation Function
char *_strupr(char* str);
unsigned char *_mbsupr(unsigned char* str);
wchar_t *_wcsupr(wchar_t* str);
_TXCHAR *_tcsupr(const _TXCHAR* str);
Internationalization (I18n) Function Overview
The _strupr function converts any lowercase characters in str to uppercase letters, using the LC_CTYPE category setting of the current locale, and returns a pointer to the converted string.
_mbsupr and _wcsupr are the multibyte and wide versions of _strupr . The argument and return value of _mbsupr are multibyte-character strings; those of _wcsupr are wide-character strings.
_tcsupr is the Windows-only Generic version of the function; with the _MBCS or _UNICODE compiler flags determining its mapping to either _mbsupr or _wcsupr .
I18n Issues
Use the appropriate version of the function as required for internationalization support, noting the following:
Ensure that the current locale is set properly.
Consider using the more secure versions of these functions, _strupr_s, _wcsupr_s, _tcsupr_s , if available.
Recommended Replacements*
*If you're already using the recommended function, see I18n Issues for other reasons why Globalyzer is detecting the function.
