|
|
The Error interface provides error handling in the form of a stack.
|
|
The <code>FUNC_ENTER()</code> macro clears the error stack whenever
|
|
an interface function is entered.
|
|
When an error is detected, an entry is pushed onto the stack.
|
|
As the functions unwind, additional entries are pushed onto the stack.
|
|
The API function will return some indication that an error occurred and
|
|
the application can print the error stack.
|
|
<p>
|
|
Certain API functions in the H5E package, such as <code>H5Eprint</code>,
|
|
do not clear the error stack. Otherwise, any function which
|
|
does not have an underscore immediately after the package name
|
|
will clear the error stack. For instance, <code>H5Fopen</code>
|
|
clears the error stack while <code>H5F_open</code> does not.
|
|
<p>
|
|
An error stack has a fixed maximum size.
|
|
If this size is exceeded then the stack will be truncated and only the
|
|
inner-most functions will have entries on the stack.
|
|
This is expected to be a rare condition.
|
|
<p>
|
|
Each thread has its own error stack, but since
|
|
multi-threading has not been added to the library yet, this
|
|
package maintains a single error stack. The error stack is
|
|
statically allocated to reduce the complexity of handling
|
|
errors within the H5E package.

)
|
|
<dt><strong>Purpose:</strong>
|
|
<dd>Turns automatic error printing on or off.
|
|
<dt><strong>Description:</strong>
|
|
<dd><code>H5Eset_auto</code> turns on or off automatic printing of
|
|
errors. When turned on (non-null <code>func</code> pointer),
|
|
any API function which returns an error indication will
|
|
first call <code>func</code>, passing it <code>client_data</code>
|
|
as an argument.
|
|
<p>
|
|
When the library is first initialized the auto printing function
|
|
is set to <code>H5Eprint</code> (cast appropriately) and
|
|
<code>client_data</code> is the standard error stream pointer,
|
|
<code>stderr</code>.
|
|
<p>
|
|
Automatic stack traversal is always in the
|
|
<code>H5E_WALK_DOWNWARD</code> direction.

|
|
<dd>Default error stack traversal callback function
|
|
that prints error messages to the specified output stream.
|
|
<dt><strong>Description:</strong>
|
|
<dd><code>H5Ewalk_cb</code> is a default error stack traversal callback
|
|
function that prints error messages to the specified output stream.
|
|
It is not meant to be called directly but rather as an
|
|
argument to the <code>H5Ewalk</code> function.
|
|
This function is called also by <code>H5Eprint</code>.
|
|
Application writers are encouraged to use this function as a
|
|
model for their own error stack walking functions.
|
|
<p>
|
|
<code>n</code> is a counter for how many times this function
|
|
has been called for this particular traversal of the stack.
|
|
It always begins at zero for the first error on the stack
|
|
(either the top or bottom error, or even both, depending on
|
|
the traversal direction and the size of the stack).
|
|
<p>
|
|
<code>err_desc</code> is an error description. It contains all the
|
|
information about a particular error.
|
|
<p>
|
|
<code>client_data</code> is the same pointer that was passed as the
|
|
<code>client_data</code> argument of <code>H5Ewalk</code>.
|
|
It is expected to be a file pointer (or stderr if NULL).
|
|
<dt><strong>Parameters:</strong>
|
|
<dl>
|
|
<dt><em>int</em> <code>n</code>
|
|
<dd>IN/OUT: Number of times this function has been called
|
|
for this traversal of the stack.
|
|
<dt><em>H5E_error_t *</em><code>err_desc</code>
|
|
<dd>OUT: Error description.
|
|
<dt><em>void</em> <code>*client_data</code>
|
|
<dd>IN: A file pointer, or stderr if NULL.
|
|
</dl>
|
|
<dt><strong>Returns:</strong>
|
|
<dd>Returns a non-negative value if successful;
|
|
otherwise returns a negative value.
