Function Documentation

int atoitok ( u8 ** p )

Extracts from a ASCII string a value (decimal or hex) and convert it to an integer value.

Blank characters are skipped
hexa values must begin with '0x' or '0X'
'-' sign is handled
returns after one value has been parsed or null character or CR character has been found.
Parameters:

p pointer to pointer to the string to be parsed. The pointer to string is modified: at the end of the call it points to the character following the last parsed one.

Definition at line 134 of file kal_codec.cpp.

void hex2ascii	(	char *	in,
		char *	out,
		u16	length
	)

Convert hexadecimal number to ascii.

Parameters:

char*	in input buffer (hex)
char*	out output buffer (ascii)
u16	len length of inoput buffer in bytes

Definition at line 74 of file kal_codec.cpp.

char* itoa	(	int	value,
		char *	result,
		int	base
	)

Converts an integer value to a null-terminated string using the specified base and stores the result in the array given by result parameter.

Parameters:

int	value integer to convert
char*	result converted string
int	base base used for conversion 2, 8, 10, 16

Returns:: A pointer to the resulting null-terminated string, same as parameter result

Definition at line 94 of file kal_codec.cpp.

s32 kal_atoi ( u8 * s )

Extracts from a ASCII string a decimal value and convert it to an integer value.

'-' sign is handled

Parameters:

s	char* string to convert

Return values:

s32	integer value

'-' and '+' signs are handled

Parameters:

s	char* string to convert

Return values:

s32	integer value

Definition at line 179 of file kal_codec.cpp.

s32 kal_atoi_float	(	u8 *	s,
		u8	d
	)

Extracts from a ASCII string a float value and convert it to an integer value * 10^number_of_decimals.

'-' and '+' signs are handled

Parameters:

s	char* string to convert
d	u8 Number of decimals

Return values:

s32	integer value

Definition at line 213 of file kal_codec.cpp.

u32 kal_atoi_hex ( u8 * s )

Extracts from a ASCII string a hex value and convert it to an integer value.

Parameters:

s	char* string to convert

Return values:

u32	integer value

Definition at line 276 of file kal_codec.cpp.

void kal_base64_decode	(	u8 *	out,
		const char *	in,
		u16	len
	)

Decode Base64-encoded buffer.

The output buffer is supposed to have enough space

Parameters:

out	u8* binary buffer result
in	char* string to decode
len	u16 string length, excluding padding

Return values:

void

Definition at line 406 of file kal_codec.cpp.

void kal_base64_encode	(	char *	out,
		u8 *	in,
		u16	len
	)

Encode Base64-encoded buffer.

The output buffer is supposed to have enough space Beware, the stream encoding is Big Endian.

Parameters:

out	char* string result
in	u8* binary buffer to encode
len	u16 length of the binary buffer in bytes

Return values:

void

Definition at line 354 of file kal_codec.cpp.

u16 kal_base64_strlen ( const char * in )

Real length (excluding padding) of Base64-encoded string Note : the input string always has 4x chars, if not return 0.

Parameters:

in	char* string to decode

Return values:

u16	string length

Definition at line 304 of file kal_codec.cpp.

u8 kal_crc8	(	u8 *	in,
		u32	len
	)

Generate crc8.

Parameters:

in	u8* input buffer
len	u32 input buffer length in bytes

Return values:

void

Generate crc8.

A table-based algorithm would be faster, but for only a few bytes it isn't worth the code size.

Parameters:

in	u8* input buffer
len	u32 input buffer length in bytes

Return values:

void

Definition at line 489 of file kal_codec.cpp.

u32 kal_ctf_decode ( kal_ctf_t ctf )

Decompress from Compressed Time Format to u32.

Parameters:

ctf	kal_ctf_t compressed value in CTF

Return values:

u32	decode result

Definition at line 577 of file kal_codec.cpp.

kal_ctf_t kal_ctf_encode	(	u32	val,
		u8	ceil
	)

Compress u32 to D7A Compressed Time format (CTF).

The ceil flag is used to define rounding, so that kal_ctf_decode(kal_ctf_encode(val, FALSE) <= val (floor) kal_ctf_decode(kal_ctf_encode(val, TRUE) >= val (ceiling)

Parameters:

val	u32 value to encode
ceil	u8 ceil value when TRUE

Return values:

kal_ctf_t compressed value

Definition at line 522 of file kal_codec.cpp.

void kal_tolower ( u8 * s )

Changes inplace to lower character a non-constant string.

Parameters:

s	u8* String to transform

Return values:

void

Definition at line 444 of file kal_codec.cpp.

void kal_toupper ( u8 * s )

Changes inplace to upper character a non-constant string.

Parameters:

s	u8* String to transform

Return values:

void

Definition at line 464 of file kal_codec.cpp.
