Public Member Functions
void	start (void) noexcept
	Starts the counter.
value_type	stop (void) const noexcept
	Stops the counter and returns the difference from start() in seconds.

Static Public Member Functions
static const char *	name (void) noexcept
	Returns the name of the counter as a C string.
static raw_value_type	read (void) noexcept
	Returns the raw value from the counter.
static constexpr value_type	normalize (raw_value_type const &v) noexcept
	Normalizes the given raw value to seconds.

Public Types
typedef struct timespec	raw_value_type
typedef double	value_type

Static Public Attributes
static const clockid_t	clk_id = STAPL_USE_CLOCK_GETTIME_ID

Detailed Description

Time counter that uses clock_gettime() in POSIX systems.

It will try to identify the best possible clock id at compile time and can be overridden only by setting the flag STAPL_USE_CLOCK_GETTIME_ID=system-provided-value.

In GNU/Linux you have to link against -lrt.
