void* memchr	(	const void *	s,
		int	c,
		size_t	n
	)

memchr - Find a character in an area of memory. : The memory area : The byte to search for
: The size of the area.

returns the address of the first occurrence of , or NULL if is not found

Definition at line 96 of file string.c.

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.

Definition at line 116 of file string.c.

char* strchr	(	const char *	s,
		int	c
	)

strchr - Find the first occurrence of a character in a string : The string to be searched : The character to search for

Definition at line 106 of file string.c.

__kernel_size_t strlen

(

const char *

s

)

strlen - Find the length of a string : The string to be sized

returns the length of

strlen - Find the length of a string : The string to be sized
