+/** @file
+ *
+ * Error codes
+ *
+ * Return status codes as used within iPXE are designed to allow for
+ * maximum visibility into the source of an error even in an end-user
+ * build with no debugging.  They are constructed as follows:
+ *
+ * Bits 7-0 : Platform-specific error code
+ *
+ * This is a losslessly compressed representation of the closest
+ * equivalent error code defined by the platform (e.g. BIOS/PXE or
+ * EFI).  It is used to generate errors to be returned to external
+ * code.
+ *
+ * Bits 12-8 : Per-file disambiguator
+ *
+ * When the same error code can be generated from multiple points
+ * within a file, this field can be used to identify the unique
+ * instance.
+ *
+ * Bits 23-13 : File identifier
+ *
+ * This is a unique identifier for the file generating the error
+ * (e.g. ERRFILE_tcp for tcp.c).
+ *
+ * Bits 30-24 : POSIX error code
+ *
+ * This is the closest equivalent POSIX error code (e.g. ENOMEM).
+ *
+ * Bit 31 : Reserved
+ *
+ * Errors are usually return as negative error codes (e.g. -EINVAL);
+ * bit 31 is therefore unusable.
+ *
+ *
+ * The convention within the code is that errors are negative and
+ * expressed using the POSIX error, e.g.
+ *
+ *     return -EINVAL;
+ *
+ * By various bits of preprocessor magic, the platform-specific error
+ * code and file identifier are already incorporated into the
+ * definition of the POSIX error macro, which keeps the code
+ * relatively clean.
+ *
+ *
+ * Functions that wish to return failures should be declared as
+ * returning an integer @c rc "Return status code".  A return value of
+ * zero indicates success, a non-zero value indicates failure.  The
+ * return value can be passed directly to strerror() in order to
+ * generate a human-readable error message, e.g.
+ *
+ *     if ( ( rc = some_function ( ... ) ) != 0 ) {
+ *         DBG ( "Whatever I was trying to do failed: %s\n", strerror ( rc ) );
+ *         return rc;
+ *     }
+ *
+ * As illustrated in the above example, error returns should generally
+ * be directly propagated upward to the calling function.
+ *
+ *
+ * Individual files may declare localised errors using
+ * __einfo_uniqify().  For example, iscsi.c declares a localised
+ * version of EACCES for the error of "access denied due to incorrect
+ * target username":
+ *
+ *     #define EACCES_INCORRECT_TARGET_USERNAME	\
+ *         __einfo_error ( EINFO_EACCES_INCORRECT_TARGET_USERNAME )
+ *     #define EINFO_EACCES_INCORRECT_TARGET_USERNAME \
+ *         __einfo_uniqify ( EINFO_EACCESS, 0x01, "Incorrect target username" )
+ *
+ * which can then be used as:
+ *
+ *     return -EACCES_INCORRECT_TARGET_USERNAME;
