/** @file
*
* Error codes
*
* Return status codes as used within iPXE 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, e.g.
*
* return -EINVAL;
*
* By various bits of preprocessor magic, the PXE 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(). For example, iscsi.c declares a localised
* version of EACCES for the error of "access denied due to incorrect
* target username":
*
* #define EACCES_INCORRECT_TARGET_USERNAME \
* __einfo_error ( EINFO_EACCES_INCORRECT_TARGET_USERNAME )
* #define EINFO_EACCES_INCORRECT_TARGET_USERNAME \
* __einfo_uniqify ( EINFO_EACCESS, 0x01, "Incorrect target username" )
*
* which can then be used as:
*
* return -EACCES_INCORRECT_TARGET_USERNAME;
*
