[tlug] shmget fails with error code = 22

["Nguyen Vu Hung" <vuhung16plus@example.com>]

Hi,

The following code has failed and the error code ( errno ) is 22.


        shmid = shmget((key_t)ShmKey, (size_t)mem_size, 0666 | IPC_CREAT);
        iErrorCode = errno;


I've checked /usr/include/asm/error.h and found that

#define EINVAL      22  /* Invalid argument */

which is not very informative.

The thing I don't know is: what argument is invalid? This code runs
"tamatama" almost perfect until today.

A reboot resolves the problem.
