Detailed Description

Control data for vectors.  This contains the number of allocated
   and used slots inside a vector.

Member Function Documentation

unsigned vec_prefix::calculate_allocation ( vec_prefix *  pfx, unsigned  reserve, bool  exact  )

static

Calculate the number of slots to reserve a vector, making sure that
   RESERVE slots are free.  If EXACT grow exactly, otherwise grow
   exponentially.  PFX is the control data for the vector.

void vec_prefix::register_overhead	(	size_t	size,
		const char *	name,
		int	line,
		const char *	function
	)

Account the overhead.

void vec_prefix::release_overhead

(

void

)

Notice that the memory allocated for the vector has been freed.
