- ALARM(2) Minix Programmer's Manual ALARM(2)
- NAME
- alarm - schedule signal after specified time
- SYNOPSIS
- #include <unistd.h>
- unsigned int alarm(unsigned int seconds)
- DESCRIPTION
- Alarm causes signal SIGALRM, see sigaction(2), to be sent to the invoking
- process in a number of seconds given by the argument. Unless caught or
- ignored, the signal terminates the process.
- Alarm requests are not stacked; successive calls reset the alarm clock.
- If the argument is 0, any alarm request is canceled. Because of
- scheduling delays, resumption of execution of when the signal is caught
- may be delayed an arbitrary amount.
- The return value is the amount of time previously remaining in the alarm
- clock.
- SEE ALSO
- pause(2), sigsuspend(2), sigaction(2), sleep(3).
