NAME
       filter_wait   - wrap waitpid to decode the exitcode and why your filter
       quit

SYNOPSIS
       #include <util/filter.h>

       NEOERR *filter_wait(pid_t pid, int options, int *exitcode);

ARGUMENTS
       pid -> the process identifier to wait for
       options -> the options to pass to waitpid (see wait(2))

DESCRIPTION
       filter_wait wraps the waitpid call and raises an error  (with  descrip‐

       the process exited with a code other  than  zero,  we  don't  raise  an

       an error
