  24 /*  SYNOPSIS */

  27         unsigned int line)

  29 /*  FUNCTION
  30         This is a function that is used for implementation of the C99 assert()
  31         function.
  32
  33     INPUTS
  34         expr - The expression to evaluate. The type of the expression does
  35                 not matter, only if its zero/NULL or not.
  36         file - Name of the source file.
  37         line - Line number of assert() call.
  38
  39     RESULT
  40         The function doesn't return.
  41
  42     NOTES
  43         Different versions of this function are available. This function
  44         is used when a program is using stdc.library but not
  45         stdcio.library or posixc.library.
  46         Because no normal DOS file I/O is available an attempt will be made
  47         to display the assertion in a requester and thus deviating from the
  48         C99 standard that says it to go to the error stream.
