Function Documentation

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

copy memory block from src to dest.

Parameters

dest	destination
src	source
size	number of bytes to copy

Warning

behaviour is undefined in case source and destination blocks overlap.

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

fill memory block with a byte value.

Parameters

s	start
c	byte fill value
n	number of bytes to fill

int strcmp	(	const char *	s1,
		const char *	s2
	)

Compare two strings.

Parameters

s1	first string
s2	second string

Returns

<0: s1<s2, ==0: s1==s2, >0: s1>s2

char* strcpy	(	char *	dest,
		const char *	src
	)

Copy null-terminated string from src to dest.

Parameters

src	source
dest	destination

Returns

pointer to dest

int strlen

(

const char *

s

)

Determine string length.

Parameters

s

string

Returns

string length
