#include #include #include int main(void) { pid_t pids; int i; for (i = 9; i >= 0; --i) { pids = fork; if (pids == 0) { sleep(i+1); _exit(0); } } for (i = 9; i >= 0; --i) waitpid(pids, NULL, 0); return 0; }

Famous quotes containing the word examples:

    “In the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.”
    —Michel de Montaigne (1533–1592)

    “Histories are more full of examples of the fidelity of dogs than of friends.”
    —Alexander Pope (1688–1744)

    “It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.”
    —G.C. (Georg Christoph)
