What is the meaning of Java Process.exitValue () values?

I use Processthrough ProcessBuilderto run an executable file made in C code. I catch Process.exitValue()to respond to these output values. I noticed that not all output values ​​from the executable file. For example, I get an output value of 139 and nowhere in my C code do I return an output value of 139.

I am trying to find an overview of the output values, but I cannot find this, and now I have found that the output value may be OS dependent. (By the way, I'm using Ubuntu).

It seems the only output value that needs to be sure is 0 when everything goes right. Are there specifications for output values? Can I be sure that a certain range can only be used for my own program? What exit codes are reserved for the OS.

I found out that 139 is probably a memory error in C code. I want to get rid of the possible. I cannot get an overview of output values ​​(e.g. 139 = .....)

This is simplified code, by the way:

ProcessBuilder p = new ProcessBuilder(executableName,
   executableArguments);
final Process shell = p.start();
InputStream shellIn = shell.getInputStream();
int shellExitStatus = shell.exitValue();

Note. Running the C executable in the Ubuntu shell does not give any error (i.e. the output value is 0). But executing the same command in Java gives an output value of 139.
