Syntax: int purecov_clear_data (void)
This function resets all data accumulators to zero. This permits you to reset coverage information after a section of the code has failed, while continuing to collect information about the session after the failure. You can also use this to ignore coverage up to a certain point--for example, if you have a function used by several parts of the code but you are specifically interested in the coverage obtained by one section of the code.
