void statistic_create

(

statistic **

stat

)

Creates and initializes a new statistic structure.

Allocates new memory for a coverage statistic structure and initializes its values.

Parameters:

stat

Pointer to newly create/initialized statistic structure

void statistic_dealloc

(

statistic *

stat

)

Deallocates memory for a statistic structure.

Destroys the specified statistic structure from heap memory.

Parameters:

stat

Pointer to statistic structure to deallocate from heap

  { PROFILE(STATISTIC_DEALLOC);

  if( stat != NULL ) {
   
    /* Free up memory for entire structure */

}

bool statistic_is_empty

(

statistic *

stat

)

Returns TRUE if the given statistic structure contains no coverage information.

Returns:

Returns TRUE if the given statistic structure contains values of 0 for all of its metrics.

Parameters:

stat

Pointer to statistic structure to check
