Hello,

I need to do some IPC with signaling between an application built with the legato application framework written in C and a NON legato, standard C executable.

My legato application does not have permissions to send signals to other processes. I tested this attempting to signal an interrupt in another process and errno returned 1(operation not permitted).

I understand it is possible to use the .api legato application framework, but this other application is too large and wasn’t architected with the legato framework in mind, so making it into a legato app would eliminate our ability to use the mangoh.

Using the legato framework, is it possible to communicate with an external process?

Thanks for your help in advance!
