Linux下递归创建目录的技术

int CreateDir(const   char   *sPathName)  
{  
   char   DirName[256];  
   strcpy(DirName,   sPathName);  
   int   i,len   =   strlen(DirName);  
   if(DirName[len-1]!='/')  
   strcat(DirName,   "/");    
   len   =   strlen(DirName);   
   for(i=1;   i<len;   i++)  
   {  
      if(DirName[i]=='/')  
       {  
          DirName[i]   =   0;  
          if(   access(DirName,   NULL)!=0   )  
           {  
               if(mkdir(DirName,   0755)==-1)  
                 {   
                      perror("mkdir   error");   
                      return   -1;   
                 }  
           }  
          DirName[i]   =   '/';  
       }  
    }  
    return   0;  
 }
