Detailed Description

Warning:
For any particular error condition, more than one of these tests may match. This is because platform-specific error codes may not always match the semantics of the POSIX codes these tests (and the corresponding APR error codes) are named after. A notable example are the APR_STATUS_IS_ENOENT and APR_STATUS_IS_ENOTDIR tests on Win32 platforms. The programmer should always be aware of this and adjust the order of the tests accordingly.

Getopt found an option not in the option string

Warning:
always use this test, as platform-specific variances may meet this more than one error code
#define APR_STATUS_IS_CHILD_DONE (   s)    ((s) == APR_CHILD_DONE)

The child has finished executing

Warning:
always use this test, as platform-specific variances may meet this more than one error code
#define APR_STATUS_IS_CHILD_NOTDONE (   s)    ((s) == APR_CHILD_NOTDONE)

The child has not finished executing

#define APR_STATUS_IS_EABOVEROOT (   s)    ((s) == APR_EABOVEROOT)

The given path was above the root path.

#define APR_STATUS_IS_EABSOLUTE (   s)    ((s) == APR_EABSOLUTE)

The given path was absolute.

#define APR_STATUS_IS_EACCES (   s)    ((s) == APR_EACCES)

permission denied

Address Family not supported

#define APR_STATUS_IS_EAGAIN (   s)    ((s) == APR_EAGAIN)

operation would block

#define APR_STATUS_IS_EBADDATE (   s)    ((s) == APR_EBADDATE)

#define APR_STATUS_IS_EBADF (   s)    ((s) == APR_EBADF)

#define APR_STATUS_IS_EBADIP (   s)    ((s) == APR_EBADIP)

#define APR_STATUS_IS_ECONNABORTED (   s)    ((s) == APR_ECONNABORTED)

Software caused connection abort

Remarks:
EPROTO on certain older kernels really means ECONNABORTED, so we need to ignore it for them. See discussion in new-httpd archives nh.9701 & nh.9603

There is potentially a bug in Solaris 2.x x<6, and other boxes that implement tcp sockets in userland (i.e. on top of STREAMS). On these systems, EPROTO can actually result in a fatal loop. See PR#981 for example. It's hard to handle both uses of EPROTO.
