NAME

       pmtimespecNow,    pmtimespecInc,    pmtimespecDec,    pmtimespecAdd,   pmtimespecSub,   pmtimespecToReal,
       pmtimespecFromReal, pmPrintHighResStamp - helper routines for time stored as a struct timespec

C SYNOPSIS

       #include <pcp/pmapi.h>

       void pmtimespecNow(struct timespec *tp);
       void pmtimespecInc(struct timespec *ap, const struct timespec *bp);
       void pmtimespecDec(struct timespec *ap, const struct timespec *bp);
       double pmtimespecAdd(const struct timespec *ap, const struct timespec *bp);
       double pmtimespecSub(const struct timespec *ap, const struct timespec *bp);
       double pmtimespecToReal(const struct timespec *tp);
       void pmtimespecFromReal(double secs, struct timespec *tp);
       void pmPrintHighResStamp(FILE *f, const struct timespec *tp);

DESCRIPTION

       pmtimespecNow is a platform-independent method that returns the current system time since  the  Epoch  in
       tp.

       pmtimespecInc adds the time in ap to the time in bp and stores the result in ap.  Similarly pmtimespecDec
       subtracts the time in bp from the time in ap and stores the result in ap.

       pmtimespecAdd (and pmtimespecSub) add (and subtract) times and return the result as a double value.   The
       time in the ap argument is not changed.

       pmtimespecToReal  converts the time in tp to an equivalent double value.  pmtimespecFromReal provides the
       reverse conversion, taking the time in secs and returning the equivalent time in tp.

       pmPrintHighResStamp prints the timestamp from tp on the stream f  in  the  local  time  (as  returned  by
       pmLocaltime(3)) in the format HH:MM:SS.XXXXXXXXX.

NOTES

       For  variants  of  these  interfaces  using  microsecond  precision  and  the timeval structure, refer to
       pmtimevalNow(3).
