how to find the end of piped data?

[Richard Sammet <richard.sammet@sit.fraunhofer.de>]

hey list,

i wrote a small tool which gets data over a pipe from other tools (like: 
cat stuff | mytool).

how can i find the end of this data stream?

at the moment im looking for a newline to see if the input is finished, 
but thats not practicable.

this is the rutine for getting the data:

      75 void scanin()
      76 {
      77    int tmpcnt=0;
      78
      79    while(sizeof(tmpkey) && tmpkey[tmpcnt-1] != 10)
      80    {
      81       tmpkey[tmpcnt]=getchar();
      82       tmpcnt++;
      83    }
      84 }

im looking for a flag like EOF but EndOfStream or something like this? ;)

anybody any idea?

e-axe
