Detailed Description

Provides some internal, more performant, but unsafe helper functions for the ZyanString data-type.

Most of these functions are very similar to the ones in Zycore/String.h, but inlined and without optional overhead like parameter-validation checks, etc ...

The ZyanString data-type is able to dynamically allocate memory on the heap, but as Zydis is designed to be a non-'malloc'ing library, all functions in this file assume that the instances they are operating on are created with a user-defined static-buffer.

Function Documentation

◆ ZydisStringAppend()

ZYAN_INLINE ZyanStatus ZydisStringAppend	(	ZyanString *	destination,
		const ZyanStringView *	source
	)

Appends the content of the source string to the end of the destination string.

Parameters

destination	The destination string.
source	The source string.

Returns: A zyan status code.

◆ ZydisStringAppendCase()

ZYAN_INLINE ZyanStatus ZydisStringAppendCase	(	ZyanString *	destination,
		const ZyanStringView *	source,
		ZydisLetterCase	letter_case
	)

Appends the content of the source string to the end of the destination string, converting the characters to the specified letter-case.

Parameters

destination	The destination string.
source	The source string.
letter_case	The desired letter-case.

Returns: A zyan status code.

◆ ZydisStringAppendDecS()

ZYAN_INLINE ZyanStatus ZydisStringAppendDecS	(	ZyanString *	string,
		ZyanI64	value,
		ZyanU8	padding_length,
		ZyanBool	force_sign,
		const ZyanStringView *	prefix,
		const ZyanStringView *	suffix
	)

Formats the given signed ordinal value to its decimal text-representation and appends it to the string.

Parameters

string	A pointer to the `ZyanString` instance.
value	The value.
padding_length	Padds the converted value with leading zeros, if the number of chars is less than the `padding_length`.
force_sign	Set `ZYAN_TRUE`, to force printing of the `+` sign for positive numbers.
prefix	The string to use as prefix or `ZYAN_NULL`, if not needed.
suffix	The string to use as suffix or `ZYAN_NULL`, if not needed.

Returns: A zyan status code.

This function will fail, if the ZYAN_STRING_IS_IMMUTABLE flag is set for the specified ZyanString instance.

◆ ZydisStringAppendDecU()

ZyanStatus ZydisStringAppendDecU	(	ZyanString *	string,
		ZyanU64	value,
		ZyanU8	padding_length,
		const ZyanStringView *	prefix,
		const ZyanStringView *	suffix
	)

Formats the given unsigned ordinal value to its decimal text-representation and appends it to the string.

Parameters

string	A pointer to the `ZyanString` instance.
value	The value.
padding_length	Padds the converted value with leading zeros, if the number of chars is less than the `padding_length`.
prefix	The string to use as prefix or `ZYAN_NULL`, if not needed.
suffix	The string to use as suffix or `ZYAN_NULL`, if not needed.

Returns: A zyan status code.

This function will fail, if the ZYAN_STRING_IS_IMMUTABLE flag is set for the specified ZyanString instance.

◆ ZydisStringAppendHexS()

ZYAN_INLINE ZyanStatus ZydisStringAppendHexS	(	ZyanString *	string,
		ZyanI64	value,
		ZyanU8	padding_length,
		ZyanBool	uppercase,
		ZyanBool	force_sign,
		const ZyanStringView *	prefix,
		const ZyanStringView *	suffix
	)

Formats the given signed ordinal value to its hexadecimal text-representation and appends it to the string.

Parameters

string	A pointer to the string.
value	The value.
padding_length	Padds the converted value with leading zeros, if the number of chars is less than the `padding_length` (the sign char is ignored).
uppercase	Set `ZYAN_TRUE` to print the hexadecimal value in uppercase letters instead of lowercase ones.
force_sign	Set to `ZYAN_TRUE`, to force printing of the `+` sign for positive numbers.
prefix	The string to use as prefix or `NULL`, if not needed.
suffix	The string to use as suffix or `NULL`, if not needed.

Returns: ZYAN_STATUS_SUCCESS, if the function succeeded, or ZYAN_STATUS_INSUFFICIENT_BUFFER_SIZE, if the size of the buffer was not sufficient to append the given value.

The string-buffer pointer is increased by the number of chars written, if the call was successful.

◆ ZydisStringAppendHexU()

ZyanStatus ZydisStringAppendHexU	(	ZyanString *	string,
		ZyanU64	value,
		ZyanU8	padding_length,
		ZyanBool	uppercase,
		const ZyanStringView *	prefix,
		const ZyanStringView *	suffix
	)

Formats the given unsigned ordinal value to its hexadecimal text-representation and appends it to the string.

Parameters

string	A pointer to the `ZyanString` instance.
value	The value.
padding_length	Padds the converted value with leading zeros, if the number of chars is less than the `padding_length`.
uppercase	Set `ZYAN_TRUE` to use uppercase letters ('A'-'F') instead of lowercase ones ('a'-'f').
prefix	The string to use as prefix or `ZYAN_NULL`, if not needed.
suffix	The string to use as suffix or `ZYAN_NULL`, if not needed.

Returns: A zyan status code.

This function will fail, if the ZYAN_STRING_IS_IMMUTABLE flag is set for the specified ZyanString instance.
