Locale-Sensitive C/C++ String Operation Function
char *_strlwr(char* str);
unsigned char *_mbslwr(unsigned char* str);
wchar_t *_wcslwr(wchar_t* str);
_TXCHAR *_tcslwr(const _TXCHAR* str);
Internationalization (I18n) Function Overview
The _strlwr function converts any uppercase characters in str to lowercase letters, using the LC_CTYPE category setting of the current locale, and returns a pointer to the converted string.
_mbslwr and _wcslwr are the multibyte and wide versions of _strlwr . The argument and return value of _mbslwr are multibyte-character strings; those of _wcslwr are wide-character strings.
_tcslwr is the Windows-only Generic version of the function; with the _MBCS or _UNICODE compiler flags determining its mapping to either _mbslwr or _wcslwr .
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, _strlwr_s, _wcslwr_s, _tcslwr_s , if available.
