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().
