<h1>Metadata Reading</h1>
<p>The Metadata API gives developers low-level access to the
information encoded in CLI modules: type and
methods definitions encoded in metadata as well as access to
the CIL code and embedded resources.
<p>Managed developers access this information using either the
System.Reflection API or a library
like <a href="http://www.mono-project.com/Cecil">Cecil</a>.
<p>To start using the Metadata API it is necessary
to <a href="mono-api-assembly.html#cil_assembly_load">open an
assembly</a> or a CIL image (a .dll or .exe file) using one of
the
<a href="mono-api-image.html#cil_image_open">CIL image
opening</a> API calls.
<h2>Metadata Heaps</h2>
<p>ECMA CLI images contain four heaps that store different
kinds of information, these are:
<ul>
<li>GUID heap (called #GUID) contains 128-bit GUIDs,
you can get pointer to a GUID value by
calling <a href="#api:mono_metadata_guid_heap">mono_metadata_guid_heap</a>.
<li>User string heap (called #US), it contains user
visible strings, you can fetch a string from this heap
by calling
<a href="#api:mono_metadata_user_string">mono_metadata_user_string</a>.
<li>Blob heap (called #blob), it contains binary
blobs of data, you can get a blob
by <a href="#api:mono_metadata_blob_heap">mono_metadata_blob_heap</a>.
You can determine the size of the blob using
the <a href="#api:mono_metadata_decode_blob_size">mono_metadata_decode_blob_size</a>.
</ul>
<p>The ECMA file format also has an extra section called the
"#~" stream, this stream is the one that holds the metadata
tables. There is a high-level API to get access to the
contents of this API, described in the
section <a href="#metadata-tables">Metadata Tables</a>.
<h4><a name="api:mono_metadata_guid_heap">mono_metadata_guid_heap</a></h4>
<h4><a name="api:mono_metadata_string_heap">mono_metadata_string_heap</a></h4>
<h4><a name="api:mono_metadata_blob_heap">mono_metadata_blob_heap</a></h4>
<h4><a name="api:mono_metadata_user_string">mono_metadata_user_string</a></h4>
<h4><a name="api:mono_metadata_decode_blob_size">mono_metadata_decode_blob_size</a></h4>
<a name="metadata-tables"/>
<h2>Metadata Tables</h2>
<p>Metadata is encoded in a number of tables included on every
CIL image. These tables contain type definitions, member
definitions and so on, these constants are defined in the ECMA 335
specification Partition II section 22. The following table
shows the C constants defined in the Mono runtime and how they
map to the equivalent ECMA CLI metadata table:
<center>

<p>Each table can contain zero or more rows, you must call the
<a href="#api:mono_metadata_table_rows">mono_metadata_table_rows</a>
to obtain the number of rows in a table, and then you can
extract individual row values by using
the <a href="#api:mono_metadata_decode_row">mono_metadata_decode_row</a>
or
the <a href="#api:mono_metadata_decode_row_col">mono_metadata_decode_row_col</a>.
When decoding rows you must provide an guint32 array large
enough to hold as many columns as the table contains.
<p>The metadata tables are stored in the MonoImage, you obtain
a pointer to the MonoTableInfo by calling
the <a href="#api:mono_image_get_table_info">mono_image_get_table_info</a>
and then you can scan those tables, for example:
<pre class="prettyprint">
/*
* Dumps a few fields from the AssemblyRef table
*/
void DumpAssemblyRefs (MonoImage *image)
{
/* Get a pointer to the AssemblyRef metadata table */
MonoTableInfo *t = mono_image_get_table_info (image, MONO_TABLE_ASSEMBLYREF);
/* Fetch the number of rows available in the table */
int rows = mono_table_info_get_rows (t);
int i;
/* For each row, print some of its values */
for (i = 0; i < rows; i++){
/* Space where we extract one row from the metadata table */
guint32 cols [MONO_ASSEMBLYREF_SIZE];
/* Extract the row into the array cols */
mono_metadata_decode_row (t, i, cols, MONO_ASSEMBLYREF_SIZE);
fprintf (output, "%d: Version=%d.%d.%d.%d\n\tName=%s\n", i + 1,
cols [MONO_ASSEMBLYREF_MAJOR_VERSION],
cols [MONO_ASSEMBLYREF_MINOR_VERSION],
cols [MONO_ASSEMBLYREF_BUILD_NUMBER],
cols [MONO_ASSEMBLYREF_REV_NUMBER],
mono_metadata_string_heap (image, cols [MONO_ASSEMBLYREF_NAME]));
}

<h2>Metadata Loading Errors</h2>
<p>The routines in this section are used to cope with errors
during metadata loading. Errors in metadata handling can
happen for many reason, and these include (this is not an
exhaustive list).
<ul>
<li>An assembly referenced is missing.
<li>Fields referenced are missing.
<li>Methods referenced are missing.
</ul>
<p>The <tt>mono_loader_set_*</tt> routines are invoked during
metadata loading to flag that an error has happened. The
class loading errros are flagged in a per-thread basis.
<P>In various spots in the runtime the
<tt>mono_loader_get_last_error</tt> routine is called to check
if there was a problem, and then errors are propagated upwards
on the stack until we reach a point where an exception can be
raised and no runtime locks are held.
<p>The <tt>mono_loader_error_prepare_exception</tt> takes a
<tt>MonoLoaderError</tt> structure (the value returned from
<tt>mono_loader_get_last_error</tt>), turns that into an
exception and clears the error condition from the current
thread.
