HP-UX Reference (11i v1 05/09) - 2 System Calls (vol 5)

shmop(2) shmop(2)

[EINVAL] shmaddr is not the data segment start address of a shared memory segment.

EXAMPLES

The following call to

shmat() attaches the shared memory segment to the process. This example

assumes the process has a valid shmid, which can be obtained by calling shmget(2).

char *shmptr;

shmptr = (char *) shmat(myshmid, 0, 0);

The following call to shmdt() then detaches the shared memory segment.

shmdt (shmptr);
