Using Keywords
where value is the appropriate value of the keyword (in this case,
the revision number).
For example, including the statement
char revnum[] = "$Revision$";
in a C source file creates a character string named revnum
containing the file’s revision number. The program can then be
configured to display this string when it starts up, automatically
presenting the current revision of the program’s source file.
Using the $Revision$ keyword to obtain the revision number of a
file is one of the common applications of keywords. Other common
applications include:
The $Header$ keyword provides a one-line summary of useful
information associated with a revision. Including this
information in a comment makes the information available to
anyone looking at the member.
The $Log$ keyword supplies the same sort of information as
$Header$ plus the revision description. The $Log$ keyword
provides a complete list of changes that have been made to the
member over time.
You can use the ident command in the command line interface to
locate and display keywords (expanded or unexpanded) in one or
more members.
This command displays the name of each member that contains
keywords, as well as the keywords themselves. This provides an
easy way to extract identification information from source files, as
well as compiled object files.
