(But seeīUGS below.) If the timer expires while the process is active Timer resolution and on the system load see time(7). Timers will never expire before the requested time, but mayĮxpire some (short) time afterward, which depends on the system Recommending the use of the POSIX timers API ( timer_gettime(2), POSIX.1-2008 marks getitimer() and setitimer() obsolete, POSIX.1-2001, SVr4, 4.4BSD (this call first appeared in 4.2BSD). ITIMER_PROF or (since Linux 2.6.22) one of the tv_usecįields in the structure pointed to by new_value contains a On error, -1 is returned, andĮRRORS top EFAULT new_value, old_value, or curr_value is not valid aĮINVAL which is not one of ITIMER_REAL, ITIMER_VIRTUAL, or The timer if both of its subfields are zero, the timer is The new_interval field specifies the new interval for If bothįields in new_value are zero, then the timer is Is armed to initially expire at the specified time. If either field in new_value is nonzero, then the timer Information that is returned by getitimer()). Return the previous value of the timer (i.e., the same If old_value is non-NULL, the buffer it points to is used to Which, by setting the timer to the value specified by new_value. The function setitimer() arms or disarms the timer specified by Single-shot timer (i.e., it expires just once). If both fields of it_interval are zero, then this is a The it_interval substructure is populated with the timer If both fields of it_valueĪre zero, then this timer is currently disarmed (inactive). Value changes as the timer counts down, and will be reset to Remaining until the next expiration of the specified timer. The it_value substructure is populated with the amount of time Specified by which in the buffer pointed to by curr_value. The function getitimer() places the current value of the timer Struct timeval it_value /* Time until next expiration */ Struct timeval it_interval /* Interval for periodic timer */ Timer values are defined by the following structures: To profile user and system CPU time consumed by theĪ process has only one of each of the three types of timers. In conjunction with ITIMER_VIRTUAL, this timer can be used The process.) At each expiration, a SIGPROF signal is Measurement includes CPU time consumed by all threads in This timer counts down against the total (i.e., both userĪnd system) CPU time consumed by the process. Time consumed by all threads in the process.) At eachĮxpiration, a SIGVTALRM signal is generated. This timer counts down against the user-mode CPU timeĬonsumed by the process. This timer counts down in real (i.e., wall clock) time.Īt each expiration, a SIGALRM signal is generated. Generates a different signal on timer expiration: Provided, each of which counts against a different clock and Three types of timers-specified via the which argument-are Timer is reset to the specified interval (if the interval is When a timerĮxpires, a signal is generated for the calling process, and the (optionally) at regular intervals after that. Timers that initially expire at some point in the future, and These system calls provide access to interval timers, that is, SYNOPSIS top #include int getitimer(int which, struct itimerval * curr_value ) int setitimer(int which, const struct itimerval *restrict new_value, struct itimerval *restrict old_value ) DESCRIPTION top Getitimer, setitimer - get or set value of an interval timer With a huge range of different species available, we find many of the red gum slabs have been milled from ringbarked trees during colonial days. The benefits of such rare timbers provide unique colours and characteristics such as size which just can't be reproduced from today's plantation timbers.GETITIMER(2) Linux Programmer's Manual GETITIMER(2) NAME top You will not find a bigger collection of slabs on the planet in which the drying process is native to the product itself and its best end use. Our slabs are dried and cured in their most natural state with 10% or less moisture content. Unlike many other infant timber suppliers, Ancient Timber Slabs by Nullarbor offer you the advantage of purchasing a product that has been seasoned by time. Rather, through our unique drying and milling process, we ensure every piece is value added to its maximum potential. It is Ancient Timber Slabs by Nullarbor's mission to ensure that these magnificent timbers are not in any way wasted, discarded or devalued. Such logs have stood the test of time through harsh weather conditions and possess incredulous durability and strength. Some of the timber logs in our yard date back over 1000 years and have been collected nationwide. Reclaimed timber is not only environmentally friendly.
