720002 is an APR error that should be caught with APR_STATUS_IS_ENOENT.
This is defined in apr_errno.h as:
Snippet
#define APR_STATUS_IS_ENOENT(s) ((s) == APR_ENOENT \
|| (s) == APR_OS_START_SYSERR + ERROR_FILE_NOT_FOUND \
|| (s) == APR_OS_START_SYSERR + ERROR_PATH_NOT_FOUND \
|| (s) == APR_OS_START_SYSERR + ERROR_OPEN_FAILED \
|| (s) == APR_OS_START_SYSERR + ERROR_NO_MORE_FILES)
and on my machine:
APR_ENOENT = 2
APR_OS_START_SYSERR = 720000
ERROR_FILE_NOT_FOUND = 2
ERROR_PATH_NOT_FOUND = 3
ERROR_OPEN_FAILED = 110
ERROR_NO_MORE_FILES = 18
So 720002 is APR_OS_START_SYSERR + APR_ENOENT.
