POSIX Timer Support

POSIX Timer Support

POSIX standard 1003.1b-1993 defines several functions related to interval timers. Of these, IRIX 6.2 supports only the alarm() function. Using this function you can cause a signal of type SIGALRM to be sent to the calling process after a specified number of seconds has elapsed. The remaining POSIX timer functions allow intervals to be specified in units of nanoseconds, for repeating intervals, and for signals at absolute times. These functions will be implemented in a release of IRIX following 6.2.
