* Error codes

7
|
7
|
*
|
|
8
|
+ * Return status codes as used within gPXE are designed to allow for
|
|
9
|
+ * maximum visibility into the source of an error even in an end-user
|
|
10
|
+ * build with no debugging. They are constructed in three parts: a
|
|
11
|
+ * PXE error code, a POSIX error code, and a gPXE-specific error code.
|
|
12
|
+ *
|
|
13
|
+ * The low byte is the closest equivalent PXE error code
|
|
14
|
+ * (e.g. PXENV_STATUS_OUT_OF_RESOURCES), and is the only part of the
|
|
15
|
+ * error that will be returned via the PXE API, since PXE has
|
|
16
|
+ * predefined error codes.
|
|
17
|
+ *
|
|
18
|
+ * The next byte is the closest equivalent POSIX error code
|
|
19
|
+ * (e.g. ENOMEM).
|
|
20
|
+ *
|
|
21
|
+ * The remaining bytes are the gPXE-specific error code, which allow
|
|
22
|
+ * us to disambiguate between errors which should have the same POSIX
|
|
23
|
+ * error code but which mean very different things to the user
|
|
24
|
+ * (e.g. ENOENT due to a DNS name not existing versus ENOENT due to
|
|
25
|
+ * a web server returning HTTP/404 Not Found).
|
|
26
|
+ *
|
|
27
|
+ * The convention within the code is that errors are negative and
|
|
28
|
+ * expressed as the bitwise OR of a POSIX error code and (optionally)
|
|
29
|
+ * a gPXE error code, as in
|
|
30
|
+ *
|
|
31
|
+ * return -( ENOENT | NO_SUCH_FILE );
|
|
32
|
+ *
|
|
33
|
+ * The POSIX error code is #defined to include the closest matching
|
|
34
|
+ * PXE error code (which, in most cases, is just
|
|
35
|
+ * PXENV_STATUS_FAILURE), so we don't need to litter the codebase with
|
|
36
|
+ * PXEisms.
|
|
37
|
+ *
|
|
38
|
+ * Functions that wish to return failure should be declared as
|
|
39
|
+ * returning an integer @c rc "Return status code". A return value of
|
|
40
|
+ * zero indicates success, a non-zero value indicates failure. The
|
|
41
|
+ * return value can be passed directly to strerror() in order to
|
|
42
|
+ * generate a human-readable error message, e.g.
|
|
43
|
+ *
|
|
44
|
+ * if ( ( rc = some_function ( ... ) ) != 0 ) {
|
|
45
|
+ * DBG ( "Whatever I was trying to do failed: %s\n", strerror ( rc ) );
|
|
46
|
+ * return rc;
|
|
47
|
+ * }
|
|
48
|
+ *
|
|
49
|
+ * As illustrated in the above example, error returns should generally
|
|
50
|
+ * be directly propagated upward to the calling function.
