PrefsFile

The module defines three functions:

• FSSpec PrefsFileSpec( Str255 )

  This function makes a FSSpec out of the name of your preferences file. The FSSpec correctly references where that file should be found in the Preferences folder of your System Folder.

• OSErr WritePrefsFile( FSSpec, Ptr, long )

  This function takes an FSSpec pointing to a file, a pointer to some data, and the length of the data in bytes. The preferences file is created, and the data is written to it. The creator of the file is defined by the global variable gPrefsCreator. This defaults to ????, but you should change it to your application's signature before calling this function.

• OSErr ReadPrefsFile( FSSpec, Ptr, long )

  This function takes an FSSpec pointing to an existing file, a pointer to a buffer, and the size of the buffer in bytes. The data from the preferences file is loaded into it.
