*
|
||||
* Error codes
|
||||
*
|
||||
* Return status codes as used within gPXE 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 in three parts: a
|
||||
* PXE error code, a POSIX error code, and a gPXE-specific error code.
|
||||
*
|
||||
* The low byte is the closest equivalent PXE error code
|
||||
* (e.g. PXENV_STATUS_OUT_OF_RESOURCES), and is the only part of the
|
||||
* error that will be returned via the PXE API, since PXE has
|
||||
* predefined error codes.
|
||||
*
|
||||
* The next byte is the closest equivalent POSIX error code
|
||||
* (e.g. ENOMEM).
|
||||
*
|
||||
* The remaining bytes are the gPXE-specific error code, which allow
|
||||
* us to disambiguate between errors which should have the same POSIX
|
||||
* error code but which mean very different things to the user
|
||||
* (e.g. ENOENT due to a DNS name not existing versus ENOENT due to
|
||||
* a web server returning HTTP/404 Not Found).
|
||||
*
|
||||
* The convention within the code is that errors are negative and
|
||||
* expressed as the bitwise OR of a POSIX error code and (optionally)
|
||||
* a gPXE error code, as in
|
||||
*
|
||||
* return -( ENOENT | NO_SUCH_FILE );
|
||||
*
|
||||
* The POSIX error code is #defined to include the closest matching
|
||||
* PXE error code (which, in most cases, is just
|
||||
* PXENV_STATUS_FAILURE), so we don't need to litter the codebase with
|
||||
* PXEisms.
|
||||
*
|
||||
* Functions that wish to return failure 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.
