OK, sounds good to me. To test if the APM suspend/timeout code was working, I just ran the following test program and suspended the machine, waited a few minutes, resumed, and then watched to see if the select() timeout fired immediately or waited the amount of time. =================================>8 cut here 8<=========================== /* * timer_test.c testing interaction between timer operation on select and APM. */ #include <sys/types.h> #include <sys/time.h> #include <unistd.h> int main(int argc, char *argv[]) { int cc; struct timeval timeout; time_t timenow; char *str_p; /* Test timeout of 45 seconds */ timeout.tv_sec = 45; timeout.tv_usec = 0; do { timenow = time(NULL); str_p = ctime(&timenow); str_p[strlen(str_p)-1] = ' '; printf("Time entering select: %s (timeout=%d)\n", str_p, timeout.tv_sec); cc = select(0, NULL, NULL, NULL, &timeout); timenow = time(NULL); str_p = ctime(&timenow); str_p[strlen(str_p)-1] = ' '; printf("Time exiting select: %s (cc= %d)\n\n", str_p, cc); } while(1); } =================================>8 cut here 8<=========================== -- Ken Key (key@cs.utk.edu) Univ. of Tennessee, Knoxville
