Hi,
I tried asking support@sidefx.com this earlier but didn't get a useful answer. Although I thank them for taking the time to respond, a list of posix signals is not what I was after.

I noticed if mantra receives a signal 9 (SIGKILL) the exit code it returns is 36608. If it receives a signal 1 (SIGHUP), the exit code it returns is 33024. It seems to return a rather large range of exit codes depending on how the process ended, be it via receiving a posix signal or internal error handling or various states of normal successful task completion.

I'm trying to automate scripting some tests to see if/how various machine types on our render farm are able to cope with mantra rendering as we've hit a few snags with certain OS revisions and machine models.

Where can I find a list of these exit code definitions?

On Unix systems, signals are mangled into the exit status. If you look at “man 2 wait”, you should see documentation for the WIFEXITED(), WEXITSTATUS() WIFSIGNALED(), etc. macros which are used to decode the verbatim exit status.

This is from the enum which can be found in $HFS/toolkit/include/UT

EXIT_OK = 0,
EXIT_GENERIC_ERROR = 1,
EXIT_BUILTIN_ERROR = 2,
EXIT_LICENSE_ERROR = 3,
EXIT_SOCKET_ERROR = 4,
EXIT_PARSE_UI_ERROR = 5

Specificly, mantra will only exit with either EXIT_OK or
EXIT_GENERIC_ERROR. Other errors may be triggered by lower level
libraries.

Note though, that an application can't handle SIGKILL, it is unconditionally terminated in that case. This means that the exit code after SIGKILL is unlikely to be useful.
