  26 # TCL procedure for READ operation testing
  27 
  28 #---------------------------------------------------------
  29 # Test procedure to Open and Read a file and check for len and EOF flag.
  30 #  Usage: ckread dfh fname off cnt expcode explen expeof prn
  31 #       dfh:     the directory filehandle where $fname located
  32 #       fname:   the filename of the file to be Opened/Read
  33 #       off:     the offset to Read
  34 #       cnt:     the count of bytes to Read
  35 #       expcode: the expected status code from the Read op
  36 #       explen:  the expected length Read
  37 #       expeof:  the expected EOF flag from Read op
  38 #       prn:     the flag to print PASS/FAIL message
  39 #
  40 #  Return: 
  41 #       0:      Write success
  42 #       -1:     things failed during the process
  43 #
