** Description: API to interval timing functions of NSPR.
**
**
** NSPR provides interval times that are independent of network time
** of day values. Interval times are (in theory) accurate regardless
** of host processing requirements and also very cheap to acquire. It
** is expected that getting an interval time while in a synchronized
** function (holding one's lock).

/***********************************************************************
** DEFINES: PR_INTERVAL_MIN
** PR_INTERVAL_MAX
** DESCRIPTION:
** These two constants define the range (in ticks / second) of the
** platform dependent type, PRIntervalTime. These constants bound both
** the period and the resolution of a PRIntervalTime.

** DEFINES: PR_INTERVAL_NO_WAIT
** PR_INTERVAL_NO_TIMEOUT
** DESCRIPTION:
** Two reserved constants are defined in the PRIntervalTime namespace.
** They are used to indicate that the process should wait no time (return
** immediately) or wait forever (never time out), respectively.
** Note: PR_INTERVAL_NO_TIMEOUT passed as input to PR_Connect is
** interpreted as use the OS's connect timeout.
