  2. VideoToolbox.pch
  3.  
  4. Use this Metrowerks CodeWarrior file to create/update the pre-compiled version
  5. of the VideoToolbox.h header. (VideoToolbox.pch won't work with THINK C; use
  6. VideoToolbox.c instead.) Adding VideoToolbox.pch to your project will cause the
  7. appropriate VideoToolbox pre-compiled header to be created or updated, if
  8. necessary, automatically. You must still write the name of the correct
  9. pre-compiled header into the prefix line of your project's "Language"
  10. Preference.
  11.  
  12. VideoToolbox.pch works only with CodeWarrior, but is more automated than
  13. VideoToolbox.c. It will automatically generate the correct file name for the
  14. precompiled header and store it in the right place. If you include this file in
  15. your project, CodeWarrior will automatically determine when the precompiled
  16. header is stale and will rebuild it automatically. Unfortunately, in CodeWarrior
  17. 5 and 6, the compiler is a bit too gung ho and always re-precompiles when you next
  18. "Make" your project after "Remove Binaries", which is a big waste of time.
  19.  
  20. All the pre-compiled headers should be stored in
  21. "VideoToolbox:VideoToolboxSources:Precompiled headers". Here's my naming
  22. convention for pre-compiled headers:
  23. "VideoToolbox.pre" = THINK C, 68k, 2-byte int, "universal" floating format w/o 8881 fpu.
  24. "VideoToolbox.f.pre" = THINK C, 68k, 2-byte int, "universal" floating format w 8881 fpu.
  25. "VideoToolbox.68k.4i.f.pre" = CodeWarrior, 68k, 4-byte int, 12-byte double for 8881.
  26. "VideoToolbox.68k.4i.pre" = CodeWarrior, 68k, 4-byte int, 10-byte double for no fpu.
  27. "VideoToolbox.ppc.pre" = CodeWarrior, PowerPC (necessarily 4-byte int and 8-byte double).
  28.  
  29. NOTE:
  30. The __option() feature was new to CodeWarrior 5 and did not work properly: it
  31. always returned false. It seems to work fine in CW5.5.
  32.  
  33. HISTORY:
  34. 1/6/95 dgp created it.
  35. 1/16/95 dgp expanded the documentation above
  36. 6/1/95 dgp updated documentation
  37. 7/19/95 dgp added special case for "ansi", which omits all Mac-specific routines.
