Create a project with the following program listing. This Lab will require an analysis of the output data to answer several of the questions.

just Looking for (MISSING CODE) , Please help

** Needed Includes

*1

#include

#include /* for printf() */

#include /* for fork() */

#include /* for wait() */

// NO_OF_ITERATIONS

// The main program

int main( int argc, char *argv[] )

// Shared memory variables

int SharedMemoryFileDescriptor; SharedMemoryType *SharedMemory;

// Common variables int i;

int rtn;

int count;

//Create the shared memory

<MISSING CODE> = shm_open(<MISSING CODE>,O_RDWR I O_CREAT,S_IRWXU S_IRWXG I S_IRWXO); if(SharedMemoryFileDescriptor == -1)

fprintf(stderr,"Can't create shared memory segment! "); fprintf(stderr,"shm_open: %s ",strerror(errno));

exit(1);

// Set the memory size

if(ftruncate(SharedMemoryFileDescriptor, sizeof(SharedMemoryType)) == -1)

{

fprintf(stderr,Cant set memory size! ");

fprintflstderr,"ftruncate: %s ",strerror(errno));

exitl(1);

}

// Map the memory, allowing read/write

<MISSING CODE> = (SharedMemoryType *) mmap{NULL,sizeof{SharedMemoryType},PROT_READ | PROT_WRITE,

MAP_SHARED,SharedMemoryFileDescriptor, 0};

if[ SharedMemory == MAP_FAILED )

{

fprintf(stderr,"Cant Map memory! "};

fprintflstderr,"mmag failed: %s ,strerror(errno)];

exitll);

}

ff Shared memory in now mapped, lets initialize it to all zeros.

If Index will point to the zero element

SharedMemory->Index=0;

forli:0;i

SharedMemory->Accessed[i]=0;

3! Create children

rtn = 1;

for( count = 0; count < 2; count++)

{

ifl rm != 0 }

{

rtn = fork();

}

else

break;

}

ff Check return value to determine if process is parent or child

if[ rtn == 0) If Child

{

{,1 We'll write to the shared memory the NO_OF_ITERAT|ONS

for(i=0;i

{

I] Write to the Shared Memory the child number (will be 1 or 2)

SharedMemory-)AccessecharedMemory->lndex]=count;

delayllO]; // To let the other processes run, problems?

SharedMemory-blndeXH;

}

// We're done with the child

}

else // Parent
