Function Documentation

int dump_registers	(	char *	buf,
		size_t	bufsize,
		const registers_t *	regs
	)

Dump the contents of a CPU registers structure to a string buffer.

Parameters

[in]	buf	Pointer to the character buffer to hold the resulting null-terminated string.
[in]	bufsize	Size of the buffer used to hold the string.
[in]	regs	Pointer to a CPU registers structure.

Returns

The number of characters that would have been written to the buffer if n had been sufficiently large.

int dump_cpuflags	(	char *	buf,
		size_t	bufsize,
		uint64_t	rflags
	)

Dump the contents of the CPU flags register.

Parameters

[in]	buf	Pointer to the character buffer to hold the resulting null-terminated string.
[in]	bufsize	Size of the buffer used to hold the string.
[in]	rflags	The 64-bit rflags register value.

Returns

The number of characters that would have been written to the buffer if n had been sufficiently large.

int dump_memory	(	char *	buf,
		size_t	bufsize,
		const void *	mem,
		size_t	memsize,
		enum dumpstyle	style
	)

Dump the contents of memory.

Parameters

[in]	buf	Pointer to the character buffer to hold the resulting null-terminated string.
[in]	bufsize	Size of the buffer used to hold the string.
[in]	mem	Pointer to the first byte of memory to dump.
[in]	memsize	Number of memory bytes to dump.
[in]	style	The output style used for the memory dump.

Returns

The number of characters that would have been written to the buffer if n had been sufficiently large.
