Function Documentation

unsigned int SBC_loadFunc	(	char *	name,
		const unsigned int *	param,
		unsigned int	index,
		BOOT_Diagnostics *	diag,
		unsigned int	funcNum
	)

Calls the specified function. Looks up the function name in the VxWorks system symbol table.

Parameters:

	name	The function symbol name.
	param	A pointer to an array of 4 function parameter words.
	index	SBC progress index MSG code.
	diag	A pointer to the boot diagnostics area.
	funcNum	A function index number for diagnostics.

Returns:

A SBC MSG code.

static unsigned int SBC_loadInflate	(	int	outFd,
		unsigned char *	inBuf,
		unsigned int	inSize,
		void *	tempBuf,
		unsigned int	index,
		BOOT_Diagnostics *	diag
	)			[static]

Inflates a ZLIB compressed image of a module file.

Parameters:

	outFd	The uncompressed output file descriptor.
	inBuf	The buffer to holding the compressed input data.
	inSize	The number of bytes of compressed input data.
	tempBuf	A temporary buffer (should be SBC_TEMP_BUF_SIZE bytes).
	index	SBC progress index MSG code.
	diag	A pointer to the boot diagnostics area.

Returns:

A SBC MSG code.

unsigned int SBC_loadModule	(	const char *	inName,
		unsigned int	id,
		unsigned char *	tempBuf,
		unsigned char *	fileBuf,
		unsigned int	index,
		BOOT_Diagnostics *	diag
	)

Invokes the VxWorks ELF object loader for the specified module. Possibly inflates the file first.

Parameters:

	inName	The path name of the module file.
	id	The file ID value.
	tempBuf	A temporary scratch buffer (SBC_TEMP_BUF_SIZE bytes).
	fileBuf	A temporary file buffer (SBC_FILE_BUF_SIZE bytes).
	index	SBC progress index MSG code.
	diag	A pointer to the boot diagnostics area.

Returns:

A SBC MSG code.
