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. |
---|
