Name

wcscmp

Synopsis

Compares two wide strings

#include <wchar.h>
intwcscmp( const wchar_t *s1, const wchar_t *s2 );

The wcscmp() function compares the wide strings addressed by its two pointer arguments, and returns a value indicating the result as follows:

Zero

The two strings are equal.

Greater than zero

The string addressed by s1 is greater than the string addressed by s2.

Less than zero

The string addressed by s1 is less than the string addressed by s2.

The wcscmp() function compares the strings one wide character at a time. As soon as it finds unmatched characters in corresponding positions in the two strings, the string containing the greater wide character value at that position is the greater string.

Example

int result = 0;
wchar_t word1[255], word2[256], *greaterlessequal;

while ( result < 2 )
{
  fputws( L"Type two words, please:  ", stdout );
  result = wscanf( L"%255l[^ ]%255ls", word1, word2 );
  if ( result == EOF )
    return EOF;
}
result =wcscmp( word1, word2 );

if ( result < 0 )
  greaterlessequal = L"less than";
else if ( result > 0 )
  greaterlessequal = L"greater than";
else
  greaterlessequal = L"the same as";

wprintf( L"The word \"%ls\" is %ls the word \"%ls\".\n", word1,
         greaterlessequal, word2 );
