Writing pointer contents into file

vinaynaikwad (32)
Hi,

I have a character pointer that points to 4000 bytes of valid data. I need to write these valid contents pointed to by this pointer into the file. I am looking for the most optimized way of doing this. I am using the below logic which seems trivial. Can anybody please suggest a better approach to accomplish the same?

/* length is the number of valid bytes of data */
void parse_contents(const char *data, int length)
{
     int j = 0;
     char path[1024] = "/tmp/data.xml";
     FILE *fp = NULL;

     fp = fopen(path, "wb");

     if (NULL != fp)
     {
          for (j = 0; j < length; j++)
          {
               fprintf(fp, "%c", *data++);
          }
     }
     else
     {
          printf("Failed to open file\n");
     }

     if (NULL != fp)
     {
          fclose(fp);
          fp= NULL;
     }
}

    fp = fopen(path, "wb");
    if (fp)

        fclose(fp);
    }
