Re: calling yyparse repeatedly

[Prabhu M.K]

yyrestart() doesn't seems to be helping. Still yylex() returing 0 after
the call of yyparse and yyrestart.

I made some changes ie., instead of using yyin, i filled the scanner
buffer with the help of function yy_scan_bytes(), which populates the
scanner buffer from another charcter buffer.

main(){
    filelen=0;
     fp = fopen("example1.xml","r");
     buffer = (char *)malloc(1024);

 while((buffer[filelen] = fgetc(fp))!=EOF)
 {
      filelen++;
 }

  if(!langparserparse()){
      printf("Test-1: parser passed\n");
      langparserrestart(NULL);
      printf("%d\n",langparserlex());
   } else
      printf("Test-1: parser failed\n");
}

Still langparserlex returning 0.
