Hi folks
There another API missing on HP NonStop and that is setitimer(), used in
progress.c and build/log.c
I do have a homebrewed implementation, on top of alarm(), it goes like this:
#include "../git-compat-util.h"
#undef getitimer
#undef setitimer
int
git_getitimer(int which, struct itimerval *value)
{
int ret = 0;
switch (which) {
case ITIMER_REAL:
value->it_value.tv_usec = 0;
value->it_value.tv_sec = alarm(0);
ret = 0; /* if alarm() fails we get a SIGLIMIT */
break;
case ITIMER_VIRTUAL: /* FALLTHRU */
case ITIMER_PROF: errno = ENOTSUP; ret = -1; break;
default: errno = EINVAL; ret = -1;
}
return ret;
}
int
git_setitimer(int which, const struct itimerval *value,
struct itimerval *ovalue)
{
int ret = 0;
if (!value
|| value->it_value.tv_usec < 0
|| value->it_value.tv_usec > 1000000
|| value->it_value.tv_sec < 0) {
errno = EINVAL;
return -1;
}
else if (ovalue)
if (!git_getitimer(which, ovalue))
return -1; /* errno set in git_getitimer() */
else
switch (which) {
case ITIMER_REAL:
alarm(value->it_value.tv_sec +
(value->it_value.tv_usec > 0) ? 1 : 0);
ret = 0; /* if alarm() fails we get a SIGLIMIT */
break;
case ITIMER_VIRTUAL: /* FALLTHRU */
case ITIMER_PROF: errno = ENOTSUP; ret = -1; break;
default: errno = EINVAL; ret = -1;
}
return ret;
}
Worth being added to compat/, e.g. as setitimer.c, or, as itimer.c (as a
by-product, it has getitimer() too)?
Bye, Jojo
