FILE   *stream; 

char   buf[1000]; 

int   filelen; 

stream=fopen( "c:\\a.txt ",   "w+ "); 

if(NULL   ==     stream)   return; 

fseek(stream,   0,   SEEK_SET); 

filelen   =   ftell(fseek(stream,   0,   SEEK_END)); 

fseek(stream,   0,   SEEK_SET); 

if(filelen   <=   sizeof(buff))   fread(buff,   filelen,   1,   stream);
