This is a built-in template used for filling the body of an implemented function when it is generated, e.g. when calling the Code | Implement Functions... function. The template is editable. Along with C++ expressions and comments, you can also use predefined variables that will be then expanded into the corresponding values.

Predefined variables will take the following values:
${RETURN_TYPE}		return type of a created function
${DEFAULT_RETURN_VALUE}		value returned by the function by default
All the predefined variables from the C File Header template (Includes tab) are also available (e.g. ${USER}, ${DATE}, etc.)
