wcscmp參數
int wcscmp( const wchar_t *string1, const wchar_t *string2 );
string1, string2 為以零值結尾的字符串所有版本的c運行庫都支持
返回值
< 0 | string1 小於string2 |
0 | string1與string2相等 |
> 0 | string1 大於 string2 wcscmp 比較寬字符 |
wcscmp函數代碼
/* STRCMP.C */
#include <string.h>

else
strcpy( tmp, "equal to" );

/* Case insensitive(could use equivalent _stricmp) */

}
wcscmp輸出結果
Compare strings:
The quick brown dog jumpsover the lazy fox
The QUICK brown dog jumpsover the lazy fox
strcmp: String1 is greater than string 2
_stricmp: String 1 isequal to string 2
