Function Documentation

KZ_HEADER_BEGIN KZ_INLINE kzString kzsStrstr	(	kzString	string1,
		kzString	string2
	)

Return a pointer to the first occurrence of string2 in string1.

KZ_INLINE kzString kzsStrchr	(	kzString	string1,
		kzChar	ch
	)

Return a pointer to the first occurrence of ch in string1.

KZ_INLINE void kzsStrcat	(	kzMutableString	head,
		kzString	tail
	)

Concatenate tail onto the end of head.

KZ_INLINE kzUint kzsStrlen ( kzString string )

Return the length of the string.

KZ_INLINE void kzsStrncat	(	kzMutableString	head,
		kzString	tail,
		kzUint	count
	)

Concatenate tail onto the end of head with at most count characters.

KZ_INLINE void kzsStrcpy	(	kzMutableString	destination,
		kzString	source
	)

Copy the source string to the destination.

KZ_INLINE void kzsStrncpy	(	kzMutableString	destination,
		kzString	source,
		kzUint	n
	)

Copy the source string to the destination.

Warning: This function does not zero-terminate the destination.

KZ_INLINE kzInt kzsAtoi ( kzString string )

Convert a string into an integer.

KZ_INLINE kzFloat kzsAtof ( kzString string )

Convert a string into a float using current locale to determine decimal separator.

KZ_INLINE kzInt kzsStrcmp	(	kzString	first,
		kzString	second
	)

Compare two strings.

Return value is 0 if the strings are equal.

KZ_INLINE kzInt kzsStrncmp	(	kzString	first,
		kzString	second,
		kzUint	n
	)

Compare the n first characters of two strings.

Return value is 0 if the strings are equal.

KZ_INLINE kzBool kzsIsSpace ( const kzChar string )

Return true if the string is a whitespace.

KZ_INLINE kzBool kzsIsDigit ( kzChar ch )

Return true if the character is a digit.

KZ_INLINE kzString kzsStrtok	(	kzMutableString	string,
		kzString	delimiters
	)

Splits string into tokens.

On a first call, the function expects a string as argument for string, whose first character is used as the starting location to scan for tokens. In subsequent calls, the function expects a null pointer and uses the position right after the end of last token as the new starting location for scanning.

Parameters

string	String to split.
delimiters	Delimiters used to split the string to tokens

Returns: Returns a pointer to the last token found in string

kzBool kzsStringFindNextCharacter	(	kzString	string,
		kzChar	ch,
		kzUint	startIndex,
		kzUint *	out_index
	)

Finds the next position where given character is located in the given string.

Search is started from the given index, which must be smaller than the length of the string. Returns false if the character is not found.

kzsError kzsStringFormatList	(	kzMutableString	string,
		kzUint	length,
		kzString	format,
		KZ_CONST_ARGLIST kzArgList *	arguments
	)

vsnprintf()-like string formatter.

Format parameter specifies how the resulting string is formatted. Arguments parameter provides the formatting arguments as variable arguments list.

See also: kzcStringFormat for format information.

kzsError kzsStringFormatGetLength	(	kzString	format,
		KZ_CONST_ARGLIST kzArgList *	arguments,
		kzUint *	out_length
	)

Get the formatted length of the string.

kzUint kzsStringGetUTF8ByteCount ( kzUnicodeChar codePoint )

Returns the number of bytes the given unicode code point requires in UTF-8 encoding.

kzUint kzsStringWriteUnicodeCharacter	(	kzMutableString	string,
		kzUint	bufferSize,
		kzUnicodeChar	character
	)

Encodes the given unicode character in UTF-8 format to the given string.

Number of bytes written is returned. 0 is returned, if the given character is invalid unicode code point. The string must be preallocated and have enough space for the necessary UTG-8 bytes of the unicode character.

kzUnicodeChar kzsStringGetUnicodeCharacter	(	kzString	string,
		kzUint *	out_byteReadCount
	)

Returns the unicode code point at the beginning of given string in UTF-8 format.

Number of bytes read for the unicode code point is stored in out_byteReadCount.
