int memcmp	(	const void *	s1,
		const void *	s2,
		int	n
	)

Compare memory (ISO C89). Assumes memory locations are same length

Parameters:

	*s1	first memory location
	*s2	second memory location
	n	length to compare

Returns:

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

Definition at line 17 of file memcmp.c.

int memcpy	(	void *	dst,
		void *	src,
		int	n
	)

Memory copy, copy a location in memory from src to dst.

Parameters:

	dst	destination location
	src	source location
	n	amount of data (in bytes) to copy

Returns:

should equal n, if not something went wrong

Definition at line 16 of file memcpy.c.

char* strcat	(	char *	,
		char *
	)

Definition at line 15 of file strcat.c.

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

Returns a pointer to the location in a string at which which a particular character appears.

Parameters:

	*s	string to search
	c	character to locate

Returns:

the pointer in the string, NULL if character not found

Definition at line 16 of file strchr.c.

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

Compare strings.

Parameters:

	*s1	first memory location
	*s2	second memory location

Returns:

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

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

Copy string s2 to s1. s1 must be large enough.

Parameters:

	s1	first string
	s2	second string

Returns:

s1

Definition at line 15 of file strcpy.c.

int strlen

(

const char *

s

)

Returns the number of non-NULL bytes in a string.

Parameters:

*s

string

Returns:

length of the string

Definition at line 14 of file strlen.c.

char* strncat	(	char *	s1,
		char *	s2,
		int	n
	)

Concatenate s2 on the end of s1. S1's space must be large enough. At most n characters are moved.

Parameters:

	*s1	first string
	*s2	second string
	n	length to concatenate

Returns:

s1

int strncmp	(	char *	s1,
		char *	s2,
		int	n
	)

Compare strings (at most n bytes).

Parameters:

	*s1	first memory location
	*s2	second memory location
	n	length to compare

Returns:

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

char* strncpy	(	char *	s1,
		char *	s2,
		int	n
	)

Copy string s2 to s1, truncating or null-padding to always copy n bytes.

Parameters:

	s1	first string
	s2	second string
	n	length of s2 to copy

Returns:

s1
