filter_wait - Man Page

#include <util/filter.h>

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

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

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

exitcode -> the exitcode if the process existed normally
