+<h1>字符串函数 - bcmp</h1>
+
+
+  <p>原型：extern int bcmp(const void *s1, const void *s2, int n);</p>
+  
+  <p>用法：#include &lt;string.h></p>
+  
+  <p>功能：比较字符串s1和s2的前n个字节是否相等</p>
+  
+  <p>说明：如果s1=s2或n=0则返回零，否则返回非零值。bcmp不检查NULL。</p>
+  
+  举例：<pre>
+
+      // bcmp.c
+      
+      #include &lt;syslib.h>
+      #include &lt;string.h>
+
+      main()
+      {
+        char *s1="Golden Global View";
+        char *s2="Golden global view";;
+        
+        clrscr();        // clear screen
+        if(!bcmp(s1,s2,7))
+          printf("s1 equal to s2 in first 7 bytes");
+        else
+          printf("s1 not equal to s2 in first 7 bytes");
+
+        getchar();
+        clrscr();
+        if(!bcmp(s1,s2,12))
+          printf("s1 equal to s2 in first 12 bytes");
+        else
+          printf("s1 not equal to s2 in first 12 bytes");
+
+        getchar();
+        return 0;
+      }
+
