CStringT::Compare 

Compares two strings (case sensitive).


int Compare(
   PCXSTR psz
) const;

Parameters

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 > > CAtlString;

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