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(). 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; * */ /* Get definitions for platform-specific error codes */ #define PLATFORM_ERRNO(_platform) <ipxe/errno/_platform.h> #include PLATFORM_ERRNO(PLATFORM) /* Get definitions for file identifiers */ #include <ipxe/errfile.h> /* If we do not have a valid file identifier, generate a compiler * warning upon usage of any error codes.
