Detailed Description

Pseudo-libC implementation.

Warning

Some of these implementations are unsafe. We know. We're not proud of this.

Function Documentation

memcpy()

void* memcpy	(	void *	destination,
		const void *	source,
		size_t	num
	)

Copies data from source to destination.

Parameters

destination	Destination address
source	Source address
num	Size of data to copy

Returns

Pointer to the destination address

memset()

void* memset	(	void *	ptr,
		int	value,
		size_t	num
	)

Sets a memory space with a single, fixed value.

Parameters

ptr	Pointer to the memory space
value	The value to write
num	The amount of memory to write to

Returns

Pointer to the memory space

strcat()

char* strcat	(	char *	dest,
		const char *	source
	)

Concatenates a source string into a destination string, assuming the destination string buffer is large enough.

Parameters

dest	Destination string buffer
source	Source string buffer

Returns

Destination string buffer, containing the concatenated strings.

strcpy()

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

String copy.

strlen()

int strlen

(

char *

str

)

String length.
