  3. *   MODULE:  EMSIF                                                         *
  4. *   OS:      DOS                                                           *
  5. *   VERSION: 1.1                                                           *
  6. *   DATE:    12/01/91                                                      *
  7. *                                                                          *
  8. *   Copyright (c) 1991 James W. Birdsall. All Rights Reserved.             *
  9. *                                                                          *
  10. *   Requires emsif.h, testutil.h, and emstest.h to compile.                *
  11. *   Compiles under Borland C++ 2.0, TC 2.0, or MSC 6.00A.                  *
  12. *                                                                          *
  13. *   Regression test and example for EMSIF.                                 *
  14. *                                                                          *
  15. *   This is part one of the regression tester and example for EMSIF.       *
  16. *   The other parts are named EMSTEST2.C and EMSTEST3.C. All three parts   *
  17. *   must be compiled and linked together along with the appropriate EMSIF  *
  18. *   library and a utilities file TESTUTIL.C to produce the tester          *
  19. *   executable. This program compiles under tiny, small, medium, compact,  *
  20. *   large, and huge models. Note that it doesn't quite fit into tiny       *
  21. *   model; the tiny model tester is actually three executables. When       *
  22. *   compiling for tiny model, one of the symbols TINYPASS1, TINYPASS2, or  *
  23. *   TINYPASS3 must be defined. See the example makefiles for further       *
  24. *   details on what needs to be linked with what to produce the tiny-model *
  25. *   executables.                                                           *
  26. *                                                                          *
  27. *   To use this tester: just run it. It requires no arguments and produces *
  28. *   output on stdout. It performs nearly 200 tests and parts of it run     *
  29. *   quite fast, even on an original IBM PC/XT (4.77 MHz). If you want to   *
  30. *   actually read the output, you should redirect the output to a file.    *
  31. *   If you just want to see whether the tests all pass, simply run it --   *
  32. *   if a test fails, execution aborts immediately.                         *
  33. *                                                                          *
  34. *   Certain types of failure may cause EMSTEST to not deallocate EMS or    *
  35. *   conventional memory that it has allocated. This should only occur if   *
  36. *   the library itself is malfunctioning (which should never happen to     *
  37. *   you, only to me!) or if you are trying a different compiler or         *
  38. *   unsupported memory model and the compiler and library are therefore    *
  39. *   not communicating properly. It may also happen if you press control-   *
  40. *   break.                                                                 *
  41. *                                                                          *
  42. *   Turbo C and older versions of Turbo C++ do not have the _fmemcmp() and *
  43. *   _fmemset() functions; I don't know about older versions of MSC. If     *
  44. *   your compiler does not have these functions, define the symbol         *
  45. *   NO_FFUNC and functions in the ancillary file TESTUTIL.C will be used   *
  46. *   instead.                                                               *
