INTRA-THREAD COMM

Can anyone point me towards a good, simple method for intra-thread communication, possibly examples in C? I don't need anything intense just simple data sharing

Inter.

posix?

It's not possible.

#include <stdio.h>

char BUFFA[5];

int main(int argc, char**argv) {
  int p;

  if ((p = fork()) > 0) {
    while(strcmp(&BUFFA, "PRINT") == 0) {
      strncpy(&BUFFA, "PRINT", 6);
    }
  } else if (p == 0) {
    while(strcmp(&BUFFA, "PRINT")) {
        printf("IPC ");
    strncpy(&BUFFA, "STOP", 5);
      }
  }
}

OH FUCK A REAL QUESTION, QUICK SAGE IT

Just use volatile and spinlocks. The x86 memory model is very forgiving.

It's not about the `reality' of the question, but the pointlessness.  You see, /prog/ has a commitment to quality, and we gain none of it by letting newbies stuff our precious board full of their naïve questions.  Take it to Google, or Usenet, or Slashdot.  Perhaps a lesser chan.  It doesn't matter to us…can't you see we're busy here?

Come back when you achieve Satori, kid.

I recommend Haskell's implementation of STM^[1].

Needs more "GRUNNUR"

I'm afraid, >>1, that inter-thread communication is impossible on shiichan. You must actually post a link to the the thread, like so: http://dis.4chan.org/read/prog/1230680782

Mutexes in pthreads not good enough for you? Look up inter process communication middle ware.
