IPC (Interprocess Communication) implementation example.

This example code illustrates the basic implementation of IPC mechanism that is provided by POSIX API.

#include shm.h>
>#include stat.h>
int main(int argc, char **argv)
int segment_id;
char *shared_mem;
const int size = 5096; // in bytes

//create shared mem.
segment_id = shmget(IPC_PRIVATE, size, S_IRUSR|S_IWUSR);

//attach the shared mem. to the process in Write Read mode.(0 argument)
shared_mem = (char * )shmat(segment_id, NULL, 0);

//write the data to the shared memory.
sprintf(shared_mem, "This is the shared memory example coded by Eren Golge. Regards!!");

//read the data from
printf("*%s n", shared_mem );

//detach the segment from process

//delete the shared mem. segment form memory
shmctl(segment_id, IPC_RMID, NULL);

printf("End of code");
return 0;
