Where is ipc.h

This function needs to be called in a loop because the remote processor may not be in a ready state. A processor must detach from all other processors before it can successfully detach from the owner of SharedRegion zero.

This function should be called within a loop to make sure the processor successfully detached from the remote processor. If called from the processor with the bigger procId, this function closes the instances created for communicating with the specified remote processor. Once the processor with the bigger procId is finished detaching, this function deletes the instances created for communicating with the specified remote processor. For BIOS, this function should be called within a 'while' loop in a Task because the slave may have to wait for the master to detach.

Ipc reserves some shared memory in SharedRegion zero for synchronization. The same amount of memory must be reserved by each processor, but only the owner of SharedRegion zero clears the reserved memory and creates the default GateMP.

The default heap for each SharedRegion is created by the owner of each SharedRegion. This function should be called only once and only after detaching from all processors.

This 'information' is passed via a pointer to shared memory with a given size and is identified via a unique tag. A typical use case of this API would be passing configuration information from a Slave core to the Host at startup-time.

For example, if MessageQ is used, this information might include the queue name, message heap sizes, etc. File List Globals. Macros Functions. Detailed Description Ipc Manager.

I have the following problem to solve: implement IPC between 3 processes in a way that the first process create the shared memory and then sends a signal to the second and third processes so they can get attached to that shared memory, now make the second process write something to the shared memory and then make it send a signal to the third process so that the third process reads what the second process had written.

Improve this question. John Smith John Smith 7 7 bronze badges. The second process doesn't have a signal handler. There may be race conditions. The signal might be coming before the signal handler is installed. The signal call to install the signal handler is deprecated. Use sigaction. Add a comment. Active Oldest Votes.
