CStringT::Compare

Compares two strings (case sensitive).

int Compare(
   PCXSTR psz
) const;

psz

The other string used for comparison.

Zero if the strings are identical, < 0 if this CStringT object is less than psz, or > 0 if this CStringT object is greater than psz.

The generic-text function _tcscmp, which is defined in TCHAR.H, maps to either strcmp, wcscmp, or _mbscmp, depending on the character set that is defined at compile time. Each function performs a case-sensitive comparison of the strings and is not affected by locale. For more information, see strcmp, wcscmp, _mbscmp.

If the string contains embedded nulls, for purposes of comparison the string is considered to be truncated at the first embedded null character.

The following example demonstrates the use of CStringT::Compare.

// typedef CStringT<TCHAR, StrTraitATL<TCHAR, ChTraitsCRT<TCHAR>>> CAtlString;

CAtlString s1(_T("abc"));
CAtlString s2(_T("abd"));
ASSERT(s1.Compare(s2) < 0);    // Compare with another CAtlString.
ASSERT(s1.Compare(_T("abe")) < 0); // Compare with LPTSTR string.
