Function Documentation

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* 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.

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

Definition at line 81 of file string.c.

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

strlcat - Append a length-limited, NUL-terminated string to another : The string to be appended to : The string to append to it
: The size of the destination buffer.

strlcat - Append a length-limited, NUL-terminated string to another : The string to be appended to : The string to append to it : The size of the destination buffer.

Definition at line 154 of file string.c.

size_t strlcpy	(	char *	dest,
		const char *	src,
		size_t	size
	)

strlcpy - Copy a NUL terminated string into a sized buffer : Where to copy the string to : Where to copy the string from : size of destination buffer

Compatible with *BSD: the result is always a valid NUL-terminated string that fits in the buffer (unless, of course, the buffer size is zero). It does not pad out the result like strncpy() does.

Definition at line 94 of file string.c.

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

strncat - Append a length-limited, NUL-terminated string to another : The string to be appended to : The string to append to it
: The maximum numbers of bytes to copy

returns a pointer to

Note that in contrast to strncpy, strncat ensures the result is terminated.

strncat - Append a length-limited, NUL-terminated string to another : The string to be appended to : The string to append to it : The maximum numbers of bytes to copy

Note that in contrast to strncpy(), strncat() ensures the result is terminated.

Definition at line 183 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.

Definition at line 116 of file string.c.

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

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

Definition at line 226 of file string.c.

char* strstr	(	const char *	s1,
		const char *	s2
	)

strstr - Find the first substring in a NUL terminated string : The string to be searched : The string to search for
