Hi,
The manual of usleep(3) states that a usleep() greater than 1,000,000
microseconds shall fail and return -1. However it does not.
[EINVAL] /microseconds/ specified a value of 1,000,000 or more
microseconds.
$ echo 'int main() { return usleep(1000001); }' | gcc -xc - && ./a.out; echo $?
0m1.03s real 0m0.00s user 0m0.02s system
0
rqt.tv_sec = useconds / 1000000;
rqt.tv_nsec = (useconds % 1000000) * 1000;
return(nanosleep(&rqt, NULL));
I think it would make more sense to remove this statement rather than changing
usleep.
