mdz_string Overview and Reference

Summary: Basically, conversion of Unicode strings between ANSI, UTF8, UTF16-LE, UTF16-BE, UTF32-LE and UTF32-BE formats are possible. This all with ANSI C89/90 conforming code, without any further dependencies!

mdz_string Advantages

1. High portability: the whole code conforms to ANSI C 89/90 Standard. Multithreading/asynchronous part is POSIX compatible (under UNIX/Linux).

2. Little dependencies: basically, mdz_string functions are only dependent on standard C-library memory-management/access functions. Multithreading part is dependent on POSIX pthreads API (under UNIX/Linux) and old process control/synchronization API (from Windows 2000). It means you can use library in your code without any further dependencies except standard platform libraries/APIs.

3. Fast: Our single-byte (ASCII/ANSI) strings are very fast, concerning operations like searching, insertion, deletion, etc. especially for very large (like hundreds of megabytes or gigabytes) strings.

4. Flexibilty: nearly all functions our single-byte (ASCII/ANSI) strings, contain not only "left position" but also "right position" parameters to limit processed area from right. Also library contains more string functions than according STL, boost or glib analogs have.

5. Extended error-checking: all functions preserve internal error-code pointing the problem. It is possible to use strict error-checking (when all preserved error-codes should be MDZ_ERROR_NONE) or "relaxed"-checking - when only returned mdz_false will indicate error.

6. Extended control: strings do only explicit operations. It means for example, when "insert" function is called - it will return error if there is not enough capacity in string. No implicit reservations will be made.

7. Attached usage: strings should not necessarily use dynamically-allocated memory - which may be not available on your embedded system (or if malloc()/free() are forbidden to use in you safety-critical software). Just attach string/data to your statically-allocated memory and use all string functionality.

8. Cache-friendly: it is possible to keep controlling and data parts together in memory using "embedded part".

9. Unicode support: UTF-8, UTF-16, UTF-32 are supported.

10. wchar_t support: also wchar_t strings are supported, with 2 and 4 bytes-large wchar_t characters.

11. Endianness-aware strings: wchar, utf16 and utf32 strings are endiannes-aware thus may be used to produce and manipulate strings with pre-defined endianness even if endianness of host differs.

12. Unicode "surrogate-pairs" awareness: 2-byte Unicode strings correctly process/distinguish "surrogate-pairs" as 1 Unicode symbol.

13. Asynchronous execution: almost all functions of single-byte (ASCII/ANSI) strings and insert functions of Unicode strings can be executed asynchronously.

mdz_utf8 General Information and Functions

mdz_utf8 is dynamically-sized contiguous string, containing UTF-8 characters

Length - actual length of string in UTF-8 symbols, excluding terminating 0.

"reserve/AndReserve" functions allocate/reallocate memory dynamically using malloc()/realloc().

mdz_wchar General Information and Functions

mdz_wchar is dynamically-sized contiguous string, containing C wchar_t characters.

Capacity - how many "wide"-characters memory is reserved for.
Size - how many "wide"-characters are actually used in a string, excluding terminating 0.
Length - actual length of string in symbols, excluding terminating 0. "surrogate pairs" count as 1 symbol.
"reserve/AndReserve" functions allocate/reallocate memory dynamically using malloc()/realloc().
"attach" functionality allows attaching contiguous block of memory to string, for using string functions on it.

UTF-16 "surrogate pairs" are supported and checked.
Unicode "combining characters" are not specially-distinguished and counted as distinct symbols.
Endianness of bytes in "wide"-character - is always endianness of platform.
Size of wchar_t in bytes - is compiler-dependend. At the moment, library supports only wchar_t with size of 2 or 4 bytes.
