ualarm
UALARM(3) BSD Library Functions Manual UALARM(3) NAME
ualarm -- schedule signal after specified time LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <unistd.h> useconds_t ualarm(useconds_t useconds, useconds_t interval); DESCRIPTION
This is a simplified interface to setitimer(2). The ualarm() function waits a count of useconds before asserting the terminating signal SIGALRM. System activity or time used in processing the call may cause a slight delay. If the interval argument is non-zero, the SIGALRM signal will be sent to the process every interval microseconds after the timer expires (e.g., after useconds number of microseconds have passed). Due to a setitimer(2) restriction, the maximum number of useconds and interval is limited to 100,000,000,000,000 (in case this value fits in the unsigned integer). RETURN VALUES
When the signal has successfully been caught, ualarm() returns the amount of time left on the clock. NOTES
A microsecond is 0.000001 seconds. SEE ALSO
getitimer(2), setitimer(2), sigpause(2), sigvec(2), alarm(3), signal(3), sleep(3), usleep(3) HISTORY
The ualarm() function appeared in 4.3BSD. BSD
