int to void. This function call exit at the end, so there is no way to return from there. Apply the same thing to the errmsg_abort function and update all components. This commit was SVN r15704.

/*
|
|
* We do NOT call the regular C-library "abort" function, even
|
|
* though that would have alerted us to the fact that this is
|
|
* an abnormal termination, because it would automatically cause
|
|
* a core file to be generated. On large systems, that can be
|
|
* overwhelming (imagine a few thousand Gbyte-sized files hitting
|
|
* a shared file system simultaneously...ouch!).
|
|
*
|
|
* However, this causes a problem for OpenRTE as the system truly
|
|
* needs to know that this actually IS an abnormal termination.
|
|
* To get around the problem, we create a file in the session
|
|
* directory - we don't need to put anything in it, though, as its
|
|
* very existence simply alerts us that this was an abnormal
|
|
* termination.
|
|
*
|
|
* The session directory finalize system will clean this file up
|
|
* for us automagically. However, it needs to stick around long
|
|
* enough for our local daemon to find it! So, we do NOT call
|
|
* session_dir_finalize here!!! Someone will clean up for us.
|
|
*
|
|
* In some cases, however, we DON'T want to create that alert. For
|
|
* example, if an orted detects that the HNP has died, then there
|
|
* is truly nobody to alert! In these cases, we pass report=false
|
|
* to prevent the abort file from being created. This allows the
|
|
* session directory tree to cleanly be eliminated.
