Question Kernel Question

Hello,

I am reading a book during my leisure time and it has the following question which I cannot find in the book:

-How are data transferred between a process and the kernel? What alternatives are available?

If you could provide some feed back it would be greatly appreciated. Thanks!

BIBLEDIT-RDWRT(1)					      General Commands Manual						 BIBLEDIT-RDWRT(1)

NAME
bibledit-rdwrt - Read or writes data to or from a Bibledit-Gtk Bible or project DESCRIPTION
Bibledit-rdwrt can read from or write to Bible data. Syntax: bibledit-rdwrt -r|-w project book chapter|0 fileName Breaking the syntax down we have: First parameter: -r|-w This can be either -r or -w which determines whether the remaining arguments are going to do a "read" operation from the specified Bibledit-Gtk Bible / project, or do a "write" operation to that Bible / project. Second parameter: project This gives the name of the Bibledit-Gtk Bible / project. All we have to do is ensure that the project name we want to access is a valid/existing one. Third parameter: book This is simply the 3-letter book code for the Bible book that is being read/written to. I.e., MAT for Matthew, GEN for Genesis, etc. Fourth parameter: chapter|0 This can be either a chapter number or 0 (zero) for reading/writing either an individual chapter or read- ing/writing a whole book (when the parameter is 0). Fifth parameter: fileName This is a temporary file name that we assign for our use with bibledit-rdwrt. For a read (-r) operation this fileName argument is the name of the file that will be created by bibledit-rdwrt containing a copy of the whole book (corresponding to the 3-letter code), or that contains the individual chapter contents (of a designated chapter) of an existing Bibledit-Gtk book file in the Bible / project. It should be prefixed with a path us. Since bibledit-rdwrt is a console operation, after AdaptIt calls it using ::wxExe- cute, it would need to read the resulting temporary file to grab the contents for its use. For a write (-w) operation this fileName argu- ment is the name of the temporary file that bibledit-rdwrt reads to get the text which it then writes to the appropriate Bible / project file. The temporary file can contain the text of a whole book, or just the text of a single chapter for the book specified by the book 3-letter code and the chapter (number) argument. bibledit-rdwrt may exit with 0 on success, or -1 on failure, as it sees fit. It may write to stdout or stderr, as it sees fit. LICENSE
