Detailed Description

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 as follows:

Bits 7-0 : PXE error code

This 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.

Bits 12-8 : Per-file disambiguator

When the same error number 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 numbers (e.g. -EINVAL); bit 31 is therefore unusable.

The convention within the code is that errors are negative and expressed using the POSIX error code and (optionally) a per-file disambiguator, e.g.

return -EINVAL;

or

define ETCP_BAD_CHECKSUM EUNIQ_02 return -( EINVAL | ETCP_BAD_CHECKSUM )

By various bits of preprocessor magic, the PXE error code and file identifier are already incorporated into the definition of the POSIX error code, which keeps the code relatively clean.

Functions that wish to return failures should be declared as returning an integer 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.
