c++ - Expected token error in file RecvFile function -

i'm learning examples c++ socket. 1 of code here has error : "expect token while got fclose" @ line above last line

the code seems fine me, can't figure out wrong here.

any ideas appreciated.

void recvfile(int sock, const char* filename)  {      int rval;      char buf[0x1000];      file *file = fopen(filename, "wb");      if (!file)     {         printf("can't open file writing");         return;     }          {         rval = recv(sock, buf, sizeof(buf), 0);         if (rval < 0)         {             // if socket non-blocking, check             // socket error wsaewouldblock/eagain             // (depending on platform) , if true             // use select() wait small period of             // time see if socket becomes readable             // again before failing transfer...              printf("can't read socket");             fclose(file);             return;         }          if (rval == 0)             break;          int off = 0;                 {             int written = fwrite(&buf[off], 1, rval - off, file);             if (written < 1)             {                 printf("can't write file");                 fclose(file);                 return;             }              off += written;         }         while (off < rval);     }       fclose(file);  }  

you have do no corresponding while:

do {     // ...         {         // ...     }     while (off < rval); }  // no while here  fclose(file);  

it appears should while (true), might stick @ top, instead of doing do while. execution break loop if recv returns 0 or less, indicate orderly shutdown , error respectively. change to:

while (true) {     // ...         {         // ...     }     while (off < rval); }  fclose(file);
