Shmget problems I used int shmget (key_t key, size_t size, int shmflg); Admission shared memory, but found the size too much time to report errornum=22 enough memory, could even even with the order to tell me I can obtain maximum shared memory?

Moreover, this can also be configured, you need to first look at the Unix platform Kernel parameter configuration sizes.
