Digest The Tortoies And The Hare

== The Tortoies And The Hare ==
I was looking for a API that could help me create a data driven model for a application I was writting at work. Since it was a Java application I turned my eyes towards [http://jakarta.apache.org Jakarta] (a true saviour for us Java coders) and found [http://jakarta.apache.org/commons/digester/ Jakarta Digester]. It seemed to full fill all that I needed. So I took it for a spin.

Sed is a very useful program that often is used as a filter in shell scripts.

From the sed man page:

Sed  is a stream editor.  A stream editor is used to perform basic text
transformations on an input stream (a file or input from  a  pipeline).

== Simple find-and-replace in text file ==
To replace all occurrences of the string ''findme'' and replace it with the string ''replcaceme'' in a file named test.file using ''sed'' just use the follwing command.

sed -e 's/findme/replaceme/g' test.fil > newtest.fil

Unused parameter warning

When using a [[wikipedia:API]] that uses callback functions there is sometimes not necessary to use at all parameters that the callback function prototype declares.

A example a API defines a callback function handleEvent as follows.
int handleFooEvent(int type, EVENT_T* event_p);

In your application you implement this function to see when a Foo Event occurs.

int handleFooEvent(int type, EVENT_T* event_p)
printf("Foo Event of type %d occured", type);
