Detailed Description

Time with millisecond precision.

The postime_t class offers system-independent time handling with millisecond precision. Using its member functions and operators, one can manipulate times in an inituive way.

Constructor & Destructor Documentation

postime_t::postime_t (   )

postime_t constructor This constructor sets the number of seconds and the number of milliseconds to zero.

postime_t::postime_t (  int  msecs  )

constructor with a number of milliseconds This constructor takes a number of milliseconds. If this number is greater than 1000, the number is split in a number of seconds and a number of milliseconds. This function is mainly useful for offsets. Parameters: msecs  Number of milliseconds See also: postime_t()

Member Function Documentation

int postime_t::after (  const postime_t &  t  )

Number of milliseconds after t. This function returns the amount of time between this time and the time specified by t. If this time is after t, this value is positive, if this time is before t, the return value is negative. Parameters: t  The time to compare with Returns: The number of milliseconds the time is after t

postime_t postime_t::operator+ (  int  t  )

time millisecond addition This function adds the given amount of milliseconds to the time and returns the result. Parameters: t  The number of milliseconds to add Returns: The result of the addition

postime_t postime_t::operator+ (  const postime_t &  t  )

time addition This function adds t to the given time and returns the result. This is probably only useful if at least one of the given times is an offset. Parameters: t  The time to add Returns: The result of the addition

postime_t& postime_t::operator+= (  int  t  )

time millisecond addition This function adds the given amount of milliseconds to the time and returns the result. Parameters: t  The number of milliseconds to add Returns: This

postime_t& postime_t::operator+= (  const postime_t &  t  )

time addition This function adds t to the given time and returns the result. This is probably only useful if at least one of the given times is an offset. Parameters: t  The time to add Returns: This

postime_t postime_t::operator- (  const postime_t &  t  )

time substraction This function substracts t from the given time and returns the result. Parameters: t  The time to substract Returns: The result of the substraction

bool postime_t::operator< (  const postime_t &  t  )

less than This operator checks whether this time is before the argument, t. Parameters: t  The time to compare with

bool postime_t::operator<= (  const postime_t &  t  )

less than or equal This operator checks whether this time is before or the same as the argument, t. Parameters: t  The time to compare with

postime_t& postime_t::operator= (  const postime_t &  t  )

time assignment This assignment operator copies the given time to the current time. Parameters: t  The time to assign Returns: The assigned time

bool postime_t::operator== (  const postime_t &  t  )

equality check This operator checks whether two times are equal, that is, both the number of seconds and the number of milliseconds are the same Parameters: t  The time to compare with

bool postime_t::operator> (  const timespec &  t  )

greater than timespec This operator checks whether the time is after the argument, t. t is a timespec, as returned by the postimespec() function, and as required by pthread_cond_timedwait function. Parameters: t  The time to compare with See also: postimespec()

bool postime_t::operator> (  const postime_t &  t  )

greater than This operator checks whether the time is after the argument, t. Parameters: t  The time to compare with

bool postime_t::operator>= (  const postime_t &  t  )

greater than or equal This operator checks whether this time is after or the same as the argument, t. Parameters: t  The time to compare with

Member Data Documentation

long postime_t::msec

number of milliseconds This is the number of milliseconds. This value can range from 0 to 999. If you assign a value greater than 999 to this, results are undefined. Definition at line 88 of file postime.h.

long postime_t::sec

number of seconds This is the number of seconds of the time. For absolute times, this is the number of seconds since the UNIX epoch as returned by the gettimeofday() function. Definition at line 79 of file postime.h.
