8 * Error codes
9 *
10 * Return status codes as used within gPXE are designed to allow for
11 * maximum visibility into the source of an error even in an end-user
12 * build with no debugging.  They are constructed as follows:
13 *
14 * Bits 7-0 : PXE error code
15 *
16 * This is the closest equivalent PXE error code
17 * (e.g. PXENV_STATUS_OUT_OF_RESOURCES), and is the only part of the
18 * error that will be returned via the PXE API, since PXE has
19 * predefined error codes.
20 *
21 * Bits 12-8 : Per-file disambiguator
22 *
23 * When the same error number can be generated from multiple points
24 * within a file, this field can be used to identify the unique
25 * instance.
26 *
27 * Bits 23-13 : File identifier
28 *
29 * This is a unique identifier for the file generating the error
30 * (e.g. ERRFILE_tcp for tcp.c).
31 *
32 * Bits 30-24 : POSIX error code
33 *
34 * This is the closest equivalent POSIX error code (e.g. ENOMEM).
35 *
36 * Bit 31 : Reserved
37 *
38 * Errors are usually return as negative error numbers (e.g. -EINVAL);
39 * bit 31 is therefore unusable.
40 *
41 *
42 * The convention within the code is that errors are negative and
43 * expressed using the POSIX error code and (optionally) a per-file
44 * disambiguator, e.g.
45 *
46 *     return -EINVAL;
47 *
48 * or
49 *
50 *     #define ETCP_BAD_CHECKSUM EUNIQ_02
51 *     return -( EINVAL | ETCP_BAD_CHECKSUM )
52 *
53 * By various bits of preprocessor magic, the PXE error code and file
54 * identifier are already incorporated into the definition of the
55 * POSIX error code, which keeps the code relatively clean.
56 *
57 *
58 * Functions that wish to return failures should be declared as
59 * returning an integer @c rc "Return status code".  A return value of
60 * zero indicates success, a non-zero value indicates failure.  The
61 * return value can be passed directly to strerror() in order to
62 * generate a human-readable error message, e.g.
63 *
64 *     if ( ( rc = some_function ( ... ) ) != 0 ) {
65 *         DBG ( "Whatever I was trying to do failed: %s\n", strerror ( rc ) );
66 *         return rc;
67 *     }
68 *
69 * As illustrated in the above example, error returns should generally
70 * be directly propagated upward to the calling function.
