<h1>字符串函数 - strdup</h1>


  <p>原型：extern char *strdup(char *s);</p>
        
  <p>用法：#include &lt;string.h></p>
  
  <p>功能：复制字符串s</p>
  
  <p>说明：返回指向被复制的字符串的指针，所需空间由malloc()分配且可以由free()释放。</p>
  
  举例：<pre><code class="language-c">


      // strdup.c
      
      #include &lt;syslib.h>
      #include &lt;string.h>

      main()
      {
        char *s="Golden Global View";
        char *d;
        
        clrscr();
        
        d=strdup(s);
        printf("%s",d);

        getchar();
        return 0;
      }
