I use lex in a dll under WinNT. The firsttime I call the lex-dll,
everything is alright. The second time, the output file contains 0
Byte. I controlled the return values of the fopen and fclose-function,
it's always alright. I also write some data "outside" the
yylex()-function into the output file. The second time I called the
lex-dll, only the data I wrote outside yylex() appeard in the output

I think the solution is inside the yylex()-function. Has anyone an idear
what can cause this problem?
