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.

int memcmp	(	const void *	cs,
		const void *	ct,
		size_t	count
	)

memcmp - Compare two areas of memory : One area of memory : Another area of memory : The size of the area.

Definition at line 68 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* strcat	(	char *	dest,
		const char *	src
	)

strcat - Append one NUL-terminated string to another : The string to be appended to : The string to append to it

returns a pointer to

strcat - Append one NUL-terminated string to another : The string to be appended to : The string to append to it

Definition at line 18 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.

int strcmp	(	const char *	cs,
		const char *	ct
	)

strcmp - Compare two strings : One string : Another string

returns 0 if and are equal, < 0 if is less than > 0 if is greater than

strcmp - Compare two strings : One string : Another string

int strncmp	(	const char *	cs,
		const char *	ct,
		size_t	count
	)

strncmp - Compare two length-limited strings : One string : Another string : The maximum number of bytes to compare

Definition at line 33 of file string.c.

char* strncpy	(	char *	dest,
		const char *	src,
		size_t	count
	)

strncpy - Copy a length-limited, NUL-terminated string : Where to copy the string to : Where to copy the string from
: The maximum number of bytes to copy

The result is not NUL-terminated if the source exceeds
bytes.

strncpy - Copy a length-limited, NUL-terminated string : Where to copy the string to : Where to copy the string from : The maximum number of bytes to copy

The result is not NUL-terminated if the source exceeds bytes.

In the case where the length of is less than that of count, the remainder of will be padded with NUL.

size_t strnlen	(	const char *	s,
		size_t	count
	)

strnlen - Find the length of a length-limited string : The string to be sized
: The maximum number of bytes to search

returns the minimum of the length of and
