apr_proc_create cleanup before exec

[Lucian Adrian Grijincu]

Hi,

(such as closing all descriptors that are not needed in the new process).

Such a feature would imply

   * changing apr_procattr_t (to add a function pointer) [on unix]
   * modifying apr_proc_create to call apr_procattr_t's internal
     pointer function if it is set [on unix]
   * modifying apr_procattr_create to initialize this pointer to NULL
     [on unix]
   * typedefing the function pointer (for readability :) )
   * adding a setter function [does noting on non-unix]



If you think this is a good idea I'll modify HEAD and post a patch.

I was wondering if you'd consider adding support for used-defined cleanup functions that would be called in the child process, just before exec(3) in apr_proc_create (on fork-ing systems). I have personalized my version of APR, but I think this is really a good feature ( + it's backwards compatible with code that does not need such a feature) and I think I'm not the only one who'd benefit from it.
