/** \defgroup codeobjectmanager Code Object Manager
 *  @{
 *
 * @brief The code object manager is a callable library that provides
 * operations for creating and inspecting code objects.
 *
 * The library provides handles to various objects. Concurrent execution of
 * operations is supported provided all objects accessed by each concurrent
 * operation are disjoint. For example, the @p amd_comgr_data_set_t handles
 * passed to operations must be disjoint, together with all the @p
 * amd_comgr_data_t handles that have been added to it. The exception is that
 * the default device library data object handles can be non-disjoint as they
 * are imutable.
 *
 * The library supports generating and inspecting code objects that
 * contain machine code for a certain set of instruction set
 * arhitectures (isa). The set of isa supported and information about
 * the properties of the isa can be queried.
 *
 * The library supports performing an action that can take data
 * objects of one kind, and generate new data objects of another kind.
 *
 * Data objects are referenced using handles using @p
 * amd_comgr_data_t. The kinds of data objects are given
 * by @p amd_comgr_data_kind_t.
 *
 * To perform an action, two @p amd_comgr_data_set_t
 * objects are created. One is used to hold all the data objects
 * needed by an action, and other is updated by the action with all
 * the result data objects. In addition, an @p
 * amd_comgr_action_info_t is created to hold
 * information that controls the action. These are then passed to @p
 * amd_comgr_do_action to perform an action specified by
 * @p amd_comgr_action_kind_t.
 *
 * Some data objects can have associated metadata. There are
 * operations for querying this metadata.
 *
 * The default device library that satisfies the requirements of the
 * compiler action can be obtained.
 *
 * The library inspects some environment variables to aid in debugging. These
 * include:
 * - @p AMD_COMGR_SAVE_TEMPS: If this is set, and is not "0", the library does
 *   not delete temporary files generated while executing compilation actions.
 *   These files do not appear in the current working directory, but are
 *   instead left in a platform-specific temporary directory (/tmp on Linux and
 *   C:\Temp or the path found in the TEMP environment variable on Windows).
 * - @p AMD_COMGR_REDIRECT_LOGS: If this is not set, or is set to "0", logs are
 *   returned to the caller as normal. If this is set to "stdout"/"-" or
 *   "stderr", logs are instead redirected to the standard output or error
 *   stream, respectively. If this is set to any other value, it is interpreted
 *   as a filename which logs should be appended to. Logs may be redirected
 *   irrespective of whether logging is enabled.
 * - @p AMD_COMGR_EMIT_VERBOSE_LOGS: If this is set, and is not "0", logs will
 *   include additional Comgr-specific informational messages.
