./src/H5Osdim.c -> H5Osdspace.c ./src/Makefile.in Changed the names of these files to better reflect what they actually do. ./src/H5.c ./src/H5AC.c ./src/H5B.c ./src/H5C.c ./src/H5D.c ./src/H5E.c ./src/H5Eprivate.h ./src/H5Epublic.h ./src/H5F.c ./src/H5Fcore.c ./src/H5Ffamily.c ./src/H5Fistore.c ./src/H5Flow.c ./src/H5Fsec2.c ./src/H5Fsplit.c ./src/H5Fstdio.c ./src/H5G.c ./src/H5Gent.c ./src/H5Gnode.c ./src/H5Gshad.c ./src/H5Gstab.c ./src/H5H.c ./src/H5M.c ./src/H5MF.c ./src/H5O.c ./src/H5Osdtyp.c (./src/H5Odtype.c) ./src/H5P.c ./src/H5T.c ./src/H5detect.c ./src/H5private.h Added an argument to the HRETURN_ERROR(), HGOTO_ERROR(), and HERROR() macros which is a string error message. This allows us to give extra information which can't be represented by the major and minor error numbers. This information was previously in comments just before or after the macro call. The string isn't currently used, but I'm planning to change the test files so they print an error trace when something fails. This should make debugging a little faster since it's often obvious what's wrong if we could just see the error stack without even having to start a debugger.

|

* Purpose: Opens a file of type TYPE with name NAME according to the

|
||
*
|
||
* H5F_ACC_WRITE: The file is open for read/write access.

* for read-only access.
|
||
*
|
||
* H5F_ACC_CREAT: The file is created if it doesn't already
|
||
* exist. On unix, the file permissions are set
|

* to 0666 modified by the umask.
|
||
*
|
||
* H5F_ACC_EXCL: This function will fail if the file already

* exists.
|
||
*
|
||
* H5F_ACC_TRUNC: Truncate the file to a zero-length file as it
|
||
* is opened. This allows existing files to be
|
||
* overwritten.
|
||
*
|
||
* The KEY argument is initialized with data which is unique to
|
||
* this file. Opening the same file (even by a different name)
|
||
* should return the same key.
|
||
*
|
||
* This is a virtual function only; the actual open operation is
|
||
* performed by the subclass. This function will fail if the
|
||
* subclass hasn't defined an open method.

*
|
||
* Errors:

|
