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
       description) if the call failed.  Note that if the ask for the exitcode
       and the process exited with a code other than zero, we don’t  raise  an
       error.  If you don’t ask for the exitcode, and it is non-zero, we raise
       an error

RETURN VALUE

       exitcode -> the exitcode if the process existed normally
