Function Documentation

memcpy2()

void * memcpy2	(	void *	dest,
		const void *	src,
		size_t	count )

Copy a block of memory, 2 bytes at a time.

Deprecated

Invokes undefined behavior. Use memcpy().

This function is identical to memcpy(), except it copies 2 bytes at a time.

Warning

This function breaks C/C++ strict aliasing rules and is no longer considered safe to use. It's also slow.

Parameters

dest	The destination of the copy.
src	The source to copy.
count	The number of bytes to copy. This should be divisible by 2 (and will be rounded down if not).

Returns

The original value of dest.

memcpy4()

void * memcpy4	(	void *	dest,
		const void *	src,
		size_t	count )

Copy a block of memory, 4 bytes at a time.

Deprecated

Invokes undefined behavior. Use memcpy().

This function is identical to memcpy(), except it copies 4 bytes at a time.

Warning

This function breaks C/C++ strict aliasing rules and is no longer considered safe to use. It's also slow.

Parameters

dest	The destination of the copy.
src	The source to copy.
count	The number of bytes to copy. This should be divisible by 4 (and will be rounded down if not).

Returns

The original value of dest.

memset2()

void * memset2	(	void *	s,
		unsigned short	c,
		size_t	count )

Set a block of memory, 2 bytes at a time.

Deprecated

Invokes undefined behavior.

This function is identical to memset(), except it sets 2 bytes at a time. This implies that all 16-bits of c are used, not just the first 8 as in memset().

Warning

This function breaks C/C++ strict aliasing rules and is no longer considered safe to use.

Parameters

s	The destination of the set.
c	The value to set to.
count	The number of bytes to set. This should be divisible by 2 (and will be rounded down if not).

Returns

The original value of dest.

memset4()

void * memset4	(	void *	s,
		unsigned long	c,
		size_t	count )

Set a block of memory, 4 bytes at a time.

Deprecated

Invokes undefined behavior. Use memset().

This function is identical to memset(), except it sets 4 bytes at a time. This implies that all 32-bits of c are used, not just the first 8 as in memset().

Warning

This function breaks C/C++ strict aliasing rules and is no longer considered safe to use.

Parameters

s	The destination of the set.
c	The value to set to.
count	The number of bytes to set. This should be divisible by 4 (and will be rounded down if not).

Returns

The original value of dest.
