Detailed Description

Utilities for common use.

Function Documentation

uint16 checksum	(	uint8 *	src,
		uint32	len
	)

Calculate checksum of a stream.

Parameters

src	The string to calculate checksum.
len	The string length.

Returns

Checksum

Definition at line 319 of file util.c.

int8 digit_length	(	int32	dgt,
		int8	base
	)

Count digit's letter Ex) digit_length(12345, 10) : This will return 5.

Parameters

dgt	The digit value to count
base	Digit base like 2, 8, 10, 16

Returns

>0: Counted digit letter

RET_NOK: Error

Definition at line 200 of file util.c.

void print_dump	(	void *	buf,
		uint16	len
	)

Print Binary Dump Data.

Parameters

buf	The data to print
len	The data length

Definition at line 288 of file util.c.

int32 str_check	(	int(*)(int)	method,
		int8 *	str
	)

Check string with standard library method.

Below is the method you can use.

• isalpha, isupper, islower
• isdigit, isxdigit, isalnum
• isspace, ispunct, isprint
• isgraph, iscntrl, isascii

Ex) str_check(isdigit, "12345") : This will return RET_OK.
Ex) str_check(islower, "AbcDe") : This will return RET_NOK.

Parameters

method	The method to use for check
str	The string to check

Returns

RET_OK: Success

RET_NOK: Error

Definition at line 233 of file util.c.

Here is the caller graph for this function:

int8* strsep	(	register int8 **	stringp,
		register const int8 *	delim
	)

Separate string into small peace by delimiter like strtok.

But if the input string contains more than one character from delimiter
in a row, strsep returns an empty string for each pair of characters from delimiter.

Ex) strsep("a,b,c,,,f,gh", ",") : When meet ,,, strtok returns 'f' but this returns NULL.

Parameters

stringp	String to separate
delim	Delimiter

Returns

Next pointer separated by delimiter
