Locale-Sensitive C/C++ String Operation Function

char *strdup(const char *strSource);

char *_strdup(const char *strSource);

wchar_t *wcsdup(const wchar_t *strSource);

wchar_t *_wcsdup(const wchar_t *strSource);

unsigned char *_mbsdup(const unsigned char *strSource);

_TXCHAR *_tcsdup(const _TXCHAR *strSource);

Internationalization (I18n) Function Overview

The strdup/_strdup functions create and return a pointer to a duplicate copy of strSource.

wcsdup/_wcsdup are the wide character equivalents; their parameters are wide-character strings.

_mbsdup is supported on Windows platforms only and is the multibyte equivalent; its parameters is a multibyte string and it returns a multibyte string.

_tcsdup is the Windows-only Generic version of the function; with the _MBCS or _UNICODE compiler flags determining its mapping to either _mbsdup or _wcsdup.

Note that the _strdup and _wcsdup functions are Microsoft Windows functions, whereas the strdup and wcsdup functions are ANSI functions.

I18n Issues

Use the appropriate version of the function as required for internationalization support.
