Detailed Description

 APR ERROR VALUES
 APR_ENOSTAT      APR was unable to perform a stat on the file
 APR_ENOPOOL      APR was not provided a pool with which to allocate memory
 APR_EBADDATE     APR was given an invalid date
 APR_EINVALSOCK   APR was given an invalid socket
 APR_ENOPROC      APR was not given a process structure
 APR_ENOTIME      APR was not given a time structure
 APR_ENODIR       APR was not given a directory structure
 APR_ENOLOCK      APR was not given a lock structure
 APR_ENOPOLL      APR was not given a poll structure
 APR_ENOSOCKET    APR was not given a socket
 APR_ENOTHREAD    APR was not given a thread structure
 APR_ENOTHDKEY    APR was not given a thread key structure
 APR_ENOSHMAVAIL  There is no more shared memory available
 APR_EDSOOPEN     APR was unable to open the dso object.  For more
                  information call apr_dso_error().
 APR_EGENERAL     General failure (specific information not available)
 APR_EBADIP       The specified IP address is invalid
 APR_EBADMASK     The specified netmask is invalid
 APR_ESYMNOTFOUND Could not find the requested symbol
 APR_ENOTENOUGHENTROPY Not enough entropy to continue

 APR STATUS VALUES
 APR_INCHILD        Program is currently executing in the child
 APR_INPARENT       Program is currently executing in the parent
 APR_DETACH         The thread is detached
 APR_NOTDETACH      The thread is not detached
 APR_CHILD_DONE     The child has finished executing
 APR_CHILD_NOTDONE  The child has not finished executing
 APR_TIMEUP         The operation did not finish before the timeout
 APR_INCOMPLETE     The operation was incomplete although some processing
                    was performed and the results are partially valid
 APR_BADCH          Getopt found an option not in the option string
 APR_BADARG         Getopt found an option that is missing an argument
                    and an argument was specified in the option string
 APR_EOF            APR has encountered the end of the file
 APR_NOTFOUND       APR was unable to find the socket in the poll structure
 APR_ANONYMOUS      APR is using anonymous shared memory
 APR_FILEBASED      APR is using a file name as the key to the shared memory
 APR_KEYBASED       APR is using a shared key as the key to the shared memory
 APR_EINIT          Ininitalizer value.  If no option has been found, but
                    the status variable requires a value, this should be used
 APR_ENOTIMPL       The APR function has not been implemented on this
                    platform, either because nobody has gotten to it yet,
                    or the function is impossible on this platform.
 APR_EMISMATCH      Two passwords do not match.
 APR_EABSOLUTE      The given path was absolute.
 APR_ERELATIVE      The given path was relative.
 APR_EINCOMPLETE    The given path was neither relative nor absolute.
 APR_EABOVEROOT     The given path was above the root path.
 APR_EBUSY          The given lock was busy.
 APR_EPROC_UNKNOWN  The given process wasn't recognized by APR
