Function Documentation

void __struct_cpy_bug

(

void

)

void* memcpy	(	void *	dest,
		const void *	src,
		size_t	count
	)

memcpy - Copy one area of memory to another : Where to copy to : Where to copy from : The size of the area.

You should not use this function to access IO space, use memcpy_toio() or memcpy_fromio() instead.

Definition at line 151 of file memcpy.c.

void* memmove	(	void *	dest,
		const void *	src,
		size_t	count
	)

memmove - Copy one area of memory to another : Where to copy to : Where to copy from : The size of the area.

Unlike memcpy(), memmove() copes with overlapping areas.

Definition at line 10 of file memmove.c.

void* memset	(	void *	s,
		int	c,
		size_t	count
	)

memset - Fill a region of memory with the given value : Pointer to the start of the area. : The byte to fill the area with : The size of the area.

Do not use memset() to access IO space, use memset_io() instead.
