Detach

I have:

int array_id;
char* records[10];

// get the shared segment
if ((array_id = shmget(IPC_PRIVATE, 1, 0666)) == -1) {
            perror("Array Creating");
}

// attach
records[0] = (char*) shmat(array_id, (void*)0, 0);
if ((int) *records == -1) {
     perror("Array Attachment");
}

which works fine, but when i try and detach i get an "invalid argument" error.

// detach
int error;
if( (error = shmdt((void*) records[0])) == -1) {
      perror(array detachment);   
}

any ideas? thank you

The following is 2 different definitions of the problem: How can I process 2 arrays so that I can keep the data of duplicate array[key] values. I have arrays A and B. I want to create array C with the children that their id/key values exist in both A and B arrays. Thank you >>> More

I'm going through a Fortran code, and one bit has me a little puzzled. There is a subroutine, say SUBROUTINE SSUB(X,...) REAL*8 X(0:N1,1:N2,0:N3-1),... ... RETURN END Which is called in another subroutine by: CALL SSUB(W(0,1,0,1),...) where W is a 'working array'. It appears that a specific… >>> More
