Data Structures
struct	timeval_T
	Redefine a timeval that has all fields signed so calculations will be simplified on rare systems that define timeval with unsigned fields. More...

Macros
#define	MILLISECONDS_MAX   ((milliseconds_T) (LONG_MAX / 1000L))
#define	ms_max(a, b)
#define	ms_min(a, b)
#define	str_to_time_t(s)
#define	TIME_PRINT_FORMAT   "ld"

Typedefs
typedef long	milliseconds_T
typedef long	time_print_T
	When formatting time_t values to be parsed with str_to_time_t(), we first cast to time_print_T and then printf() the result with TIME_PRINT_FORMAT.

Functions
timeval_T *	timeval_from_milliseconds (timeval_T *t, milliseconds_T milliseconds)
timeval_T *	timeval_from_seconds (timeval_T *t, long seconds)
timeval_T *	timeval_from_double (timeval_T *t, double x)
milliseconds_T	sec_to_ms (long sec)
